Hi @shavora,
I see that code might be coming from one of my blogs 😁. It has been a while since I checked if it still works (Sep 2021).
Just tested it, it should still work. Only difference is that I would now use the v1.0 endpoint, not the beta.
Btw, this should also be possible via the Send an HTTP request (Office 365 Groups connector) action, which is non-premium 😉
1. My setup of today. Same json payload.

2. Test result today.
