Become Tenant option is not Enabling

I see the disconnect. My responses have been geared toward an on premises installation of Orchestrator. Based on the screenshot you have included, it appears you’re trying to access UiPath’s cloud based Orchestrator (i.e., Community Edition). I don’t have experience using the cloud platform (actually get an error just trying to sign-in), so the best I can do is refer you to this post where they discuss the sign-in process, but stop just short of telling you how to create create a tenant. That said, if you click on “Services”, you should see the “Add Service” button which, I guess, would allow you to create a tenant. Sorry I cannot be of further assistance.
