How to use Social-Auth-Django-App with Facebook's https://m.me/ - django

Question

I tried using hyperlink and supplied it with my actual Facebook Username and it's working. But the problem is my actual Facebook Username is different from the Username provided by Social-Auth-App-Django. So I tried User ID instead but it's not working either.
By the way what I'm trying to do is an online shopping website and when a user clicks the hyperlink, he/she will be redirected to the seller's Facebook Messenger account to start a conversation.
This is the first line of code that I tried which is working.
Send Message to Seller
And this is the code I used using Social-Auth-App's provided data:
Send Message to Seller
And I also tried this:
Send Message to Seller
Any idea how I can use Facebook's m.me/ using the provided data by Social-Auth-App-Django? Or if you can suggest me other ways other than m.me/ I will greatly appreciate it. Thank you very much!
