How to get membera from an embed already written by a bot?

Question

Node.js

I'm trying to get a user on a successful bump through a monitoring bot.
If, after a successful Up, there is a user.tag in the embed (in the setAuthor or setFooter section), then everything successfully translates and receives its id.
Example:

let member = message.guild.members.cache.find(member => member.user.tag == message.embeds[0].author.name);

or

let member = message.guild.members.cache.find(member => member.user.tag == message.embeds[0].footer.text);

But getting the user from the mention does not work.

Answer 1

let member = message.guild.members.cache.find(member => message.member.user.id == m.embeds[0].description.replace(/\D+/g,""));
