How to set up ArcGIS Pro in a classroom with same credidentaials on all of the computers?

[DEMÉKVKI]

I found several useless workflows on the labyrinth of the Esri websites about how to install ArcGIS Pro on 30 computers with concurrent users or similar user/pass pairs. I cannot even download any license server program; the program doesn't appear in the places where these workflows would indicate.

Any idea?

If you haven't done so already, the following documents provide the steps to download and authorize Concurrent Use Pro licenses.

Thank You, but I still can't fix this problem since I have no right to download the Licence Manager from My Esri.

When I log in with the institute's main admin account (this one) to My Esri, I still have to request access to join my organisation or provide a token.
