Due to the new Role Based admin usage, you can no longer create a custom role easy. Before I go off and make attempts, did anyone create a read-only role already perhaps? Could you share what you did?
I believe I will need to follow THIS KB, and then do 'trial and error'
No. Not yet at least. I need to find proper time. I have a few minutes here and there, and need to have a dedicated slot available. I am not sure about actually adding a new role. I was more leaning to adjusting a role we don't use in our EV.
As soon as I have found what needs to be done, I'll post that here.
