Hey Developers;
I want to assign other users of the portal with different web roles by the Admin user of the portal in the dynamics portal, I have achieved this by using Workflow in the Entity form for single web role, the issue with workflow is, for every web role assign to the user I have to create a custom workflow button in the portal in entity form for the user. Is any way to give the Admin user that he/she can select multiple web roles to assign to the user and this can be achieved from the portal itself.
As in bellow screen shorts, it might be clear.
"Assign web role" is a custom on-demand workflow

Workflow

I want to show all web roles to the portal so that the Admin user can Assign multiple web roles / any web role from that list.
Please help somebody.
