Flow Button Not Visible

System Settings
Navigate to Settings > Administration. Go to System Settings

In System Settings, under Customization tab, look for Enable Microsoft Flow option.

You’ll be asked for permission

Now, this is turned on

Flow Button Visible
Now, once you have enabled this setting, you’ll be able to see the Flow button on the View and Form ribbons across Dynamics 365 CE

That was quick!!
