Getting an ID from newly created user

I am using the Joomla save user form.
I'm creating a new user and creating a new group using the account_name variable.
Under the submit tab, query the db to get the newgroupID. (Could not figure out how to use joomla to do it)
What I'm having trouble with is getting the id of the newly created user. Below is the code in the php9 block and the debug output.
All assistance with getting the userid and properly creating the group would be appreciated..

Array

    [app_active_page] => 0
