Valet / localhost/callback testing

Hi

I've got a test environment running on my laptop, I'm creating a test app to implement microsoft graph api.

The instructions are:-

https://docs.microsoft.com/en-us/graph/tutorials/php?tutorial-step=1

In step 2 it shows the call back web uri:-

http://localhost:8000/callback

BUT, as I am using Valet, my url is:- http://graph-tutorial.test

I cannot put:- http://graph-tutorial.test/callback

My question today is, how do I configure Azure as Valet is not using localhost but my foldername.test??

Cheers in advance Carl.
