Does the Monzo Auth allow my app to confirm payments with the Open Banking API?

I’m talking with a client that has an OB authorization and he has a question which is:
If the client of the application authorizes the app by going to Monzo, can the app then make further payments with the Open Banking API without the need to request approval of the user?

I think each request made requires approval - it isn’t a one time thing.

I’ve been reading the docs and it seems that this is right.
Does the AISP and PISP requests differ? If the user grants my app access to his account, will he also need to approve a payment?

Also, is the AISP request a one time thing?
