Increase limit of get group members

[algreen88]

I have a Flow which adds users to a group but does a check prior to adding the user to the group by using the Azure AD Get Group Members function. Sadly, there is a limit on this group (maybe 999?) and the group I want to do the check on has thousands of members, which causes my Flow to fail. 

By increasing the limit will help me not introduce manual or cumbersome workarounds.
