System Center Orchestrator 2022

I have automations set up for user terminations. When a user is termed, i want to be able to give the manager access to their one drive (sharepoint module issues).

The way i am authenticating is with a cert, app-only authentication. the problem that i have found with connect-sposervice is that the module is older than the connect-exchange online module and it only looks in the current users cert store so when i run a command it says it cant find it. so Ok, i connected to powershell with the orchestrator service account and imported the cert to that local store but it still didnt work.

I then tried to use the newer powershell module, connect-pnponline but that requires powershell 7.x.x to even run and orchestrator is using powershell 5 (at least its 64 bit) 

So i then try to run powershell 7 with a run .net activity but when i use orchestrator variables, it just comes out as garbled text since the activity isnt the one running the command. 

Any suggestions on how i make this work? 

As i have said, i just need orchestrator to be able to assign the manager as full control over a terminated user's onedrive. The exchange modules work great for app only auth, but the sharepoint ones just arent working for me. I used to pass a password using basic auth but that is now deprecated, (and its not a good practice to do that anyways).

Thank you so much in advance for any tips or tricks to get this working.
