Display profile info in user's comments

I am trying to figure out how to display information about a user from their profile (for example, Biographical Info) when they comment.

I have searched the forum and found Displaying User Profile Descriptions In Comments but it’s 5 years old and the topic is closed.

I’ve also found Logged-in user’s comments – display email/website info from his User Profile but it doesn’t really help me at all because I need actual instructions on how to implement the solution (I am not a developer).

Does anyone here know how to pull this info from the commenter’s profile and display it beneath the commenter’s user or display name? Any help is appreciated.
