If you have had Dynamics 365 prior to October 2019 with the Unified Interface you may have noticed the option to run on-demand workflows has vanished from the form ribbon. This is easy to enable, and any new instances will have this enabled by default.
To enable or disable Power Automate integration in your organization, follow these steps.
You will now notice you have the the flows menu icon where you can run Flows and legacy Workflows on demand.
