In my previous article, i have explained about How to Enable Microsoft Power Automate in Dynamics CRM UCI?

Even, this Power Automate setting is Enabled, Other than System Administrator, no other security roles users are not able to see this Flow button.

After a research, found that there is a privilege named Run Flows under Customization, that we have to provide access on it explicitly, to the required security roles.

Hope you got this setting and give this privilege on the required Security roles for the Users, who wants to work on the Flows.
