Can I use this with the Microsoft Graph API?

[fideloper]

Hi!
I'm a bit confused by Microsoft's offering. I'm using Firebase/JWT right now to attempt to get a token to use with Microsoft Graph API's (I have the secret key working, but am attempting to use certificate based auth instead).

Is this library suitable for that use case instead, or is it for something else?

Currently with the Firebase/JWT, I'm working through errors of it not thinking I have the correct Key being used (different/wrong thumbprint).
