Decoding gmail embedded images in ClickUp tasks description not working

I’m trying to do this workflow with Pipedream:

• A Gmail account receives an email.
• The message from the email is decoded, using the “text/plain” part (if it doesn’t exist, I use the “text/html”).
• Create a ClickUp task or update an existing one with that message.
• Download attachments (not the embedded images, if i include them and upload those too, the task ended up with signatures images, logos, etc as upload files, when i need them to be in the description of the task ).
• Upload those attachments.

The thing is that decoding messages with embedded images is not working properly because embedded images can’t be decoded with base64.

Is there a way to create the task with the description being the exact same email, with embedded images and all those kinds of things? Like i said before, i’ve tried to download those images as attachments and upload them, but the task ended up with those images as uploaded files; I need them to be in the description as embedded images.

This is how I decode the email:

import { htmlToText } from "html-to-text";

const decodeBase64 = (data) => {
  const normalizedBase64 = data.replace(/-/g, '+').replace(/_/g, '/');
  const padding = normalizedBase64.length % 4;
  if (padding > 0) {
    normalizedBase64 += '='.repeat(4 - padding);
  }
  return Buffer.from(normalizedBase64, 'base64').toString('utf-8');
};

export default defineComponent({
  async run({ steps, $ }) {
    const email = steps.trigger.event.payload;
    const text = {
      mimeType: "",
      data: "",
    }
    const parts = email.parts;

    if(email.mimeType.includes("multipart")){
      function findEmailText(parts){
        for(const part of parts){
          const subParts = part.parts;
          if(subParts){
            findEmailText(subParts);
          }
          if(part.mimeType === "text/plain" || part.mimeType === "text.html"){
            text.mimeType = part.mimeType;
            text.data = part.body.data;
            break;
          }
        }
      }
      findEmailText(parts);
    } else {
      text.mimeType = email.mimeType;
      text.data = email.body.data; 
    }

    text.decodedMessage = text.mimeType !== "text/html" ? decodeBase64(text.data) : htmlToText(decodeBase64(text.data), { wordwrap: 130 });
    
    return text.decodedMessage;
  },
})

And how i upload the attachments:

import { axios } from "@pipedream/platform"
import fs from "fs";
import FormData from "form-data";

export default defineComponent({
  props: {
    clickup: {
      type: "app",
      app: "clickup",
    }
  },
  async run({ steps, $ }) {

    const { TMP_DIR } = steps.define_constants.$return_value;
    const taskId = steps.if_task.$return_value;
    const files = steps.download_attachments.$return_value;
    for (let i = 0; i < files.length; i++) {
      const file = files[i];
      const filePath = `${TMP_DIR}/${file.filename}`;
      const fileStream = fs.createReadStream(filePath);
      
      const formData = new FormData();
      formData.append(`attachment`, fileStream); 

      try {
        await axios($, {
          method: 'POST',
          url: `https://api.clickup.com/api/v2/task/${taskId}/attachment`,
          headers: {
            Authorization: `${this.clickup.$auth.oauth_access_token}`,
            ...formData.getHeaders(),
          },
          data: formData,
        });
      } catch (error) {
        console.error('Error message:', error.message);
      }
    }
  
    return `Uploaded ${files.length} files successfully.`;
  }
})
