Group Forms in Dynamics 365 Environment

We have set up forms in the default Forms Pro environment. We want to now use these in the Dynamics 365 environment but the option for Group Forms is not available once we change environments.  See screenshots below...

Is there any way to enable this or create new groups that show up in the Dynamics 365 environment?

Any assistance would be greatly appreciated.
