Discord.js client mention and text behind command

I want it to ping the client who sent the message and to write the text after the command. Please help, thank you.

client.on("messageCreate", function(message) {
    if (!message.content.startsWith(prefix)) return;

    const commandBody = message.content.slice(prefix.length);
    const args = commandBody.split(' ');
    const command = args.shift().toLowerCase();
    const channel = client.channels.cache.get('939145964961292298');
    message.delete()

    if ("napad") {
        const { MessageEmbed } = require('discord.js');
        const exampleEmbed = new MessageEmbed()
            .setColor('#6d4193')
            .setTitle('mention sender')
            .setDescription('message after command')
            .setTimestamp()
            .setFooter({ text: 'PixelRP | BOT by ejdamec', iconURL: 'https://cdn.discordapp.com/attachments/939271126784303104/939453115810320414/logo_pure.png' });

        channel.send({ embeds: [exampleEmbed] });
    }
});
