I need a detailed explanation of how to give Messenger permission to access stored credentials…

Please!!!

What is this FaceBook(?) third party...Messenger

make some changes(?)

System Settings > Privacy & Security > Privacy> Full Disk Access(?)

check the box next to "Facebook Messenger" to grant it access

report back your success or failure

FaceBook Support may be more insightful.
