Hi @sampathgelli,
For permissions, you need to go to below screen tenant->manage access->find/create role and set permissions.
For licenses, you need to go tenant->licenses->and assign license there to your machine. If you don’t have any non-prod licenses, you can assign unattended license along with testing license, should work with that too.
Alternatively, licenses can also be assigned while create machine activity so you can go to your machine that you have created under tenant->machines-> go to your machine → edit licenses
