Hi @jr123456 

If you need to query for O365 groups you should be able to use the Microsoft Office Groups to create a data source if you don’t already have one.
 

Then in the form you can use the new single choice dropdown with a data source variable:

 

add a single choice control, remove the options and change to dropdown:

 

Go to insert, external data and navigate to the Records collection inserting that:

 

Select Name and ID as below:
​​​​​​​

It is always preferred to select ID as a value as this can then be used further in the workflow to get members etc but there is nothing stopping you from using Name Name, I have also noted that there doesn’t appear to be any filtering options for this query so I will see what I can do to get this changed as typically the next step would be to have another data source variable filtered to the selected item to return its properties. 
 

Hi @jr123456 

Has this reply solved your question? 

Hi @jr123456 

Just to follow up on update to this, I have made the changes to the connector needed to allow for selected groups to be returned individually to get information such as name.
 

 
I have submitted this to the product team and can only wait for it to be reviewed and released, no ETA I am afraid.
