Sonarqube – Error Refactor this function to reduce its Cognitive Complexity from 18 to the 15 allowed – in javascript

I am getting this error :
30:9 error Refactor this function to reduce its Cognitive Complexity from 18 to the 15 allowed

Possible solutions I tried is like using if and then else if for the rest of the conditions.
Error will go but my code will not work as expected

How can I refactor the below code?

 workItemDetails.value.map((e: any) => {
        const existingData = touchPointRequests.filter((t) => +t.ticket_no === e.id);
        if (existingData.length && e.fields['System.State']) {
          this.updateBrandWebsiteState(existingData, e.fields['System.State']);
        }
        const existingGoLiveDate = new Date(new Date(existingData[0].go_live_date).toDateString());
        const newGoLiveDate = new Date(new Date(e.fields['Custom.GoLiveDate']).toDateString());
        const updateData: any = {};
        if (
          existingData.length &&
          e.fields['Custom.GoLiveDate'] &&
          newGoLiveDate.getTime() !== existingGoLiveDate.getTime()
        ) {
          const zonedDate = utcToZonedTime(new Date(e.fields['Custom.GoLiveDate']), 'Europe/Berlin');
          updateData.goLiveDate = zonedDate;
        }
        if (
          existingData.length &&
          e.fields['Microsoft.VSTS.Common.Priority'] &&
          AzurePriority[e.fields['Microsoft.VSTS.Common.Priority']] !== existingData[0].priority
        ) {
          updateData.priority = AzurePriority[e.fields['Microsoft.VSTS.Common.Priority']];
        }

        if (Object.keys(updateData).length) {
          this.touchPointRequestRepository.UpdateTouchPointRequestById(existingData[0].tpr_id, updateData);
        }
        if (
          existingData.length &&
          e.fields['Custom.PreviewLinks'] != undefined &&
          existingData[0].preview_link !== e.fields['Custom.PreviewLinks']
        ) {
          this.brandWebsiteRequestRepository.UpdateBrandWebsiteRequestByTPId(existingData[0].tpr_id, {
            previewLink: e.fields['Custom.PreviewLinks'],
          });
          this.sendPreviewLinkUpdateMail(existingData);
        }

        if (
          existingData.length &&
          e.fields['System.State'] === 'In Review' &&
          e.fields['Custom.PreviewLinks'] != undefined &&
          existingData[0].feedback_and_comments !== e.fields['Custom.PreviewLinks']
        ) {
          this.brandWebsiteRequestRepository.UpdateBrandWebsiteRequestByTPId(existingData[0].tpr_id, {
            feedbackAndComments: e.fields['Custom.PreviewLinks'],
          });
        }
      });
