How to Add cloud users to group after disabling DirSync?

I have decommisioned my on-prem exchange 2007 server and want to manage users and groups via cloud admin console.

I followed guidance from "How and when to decommission your on-premises Exchange servers in a hybrid deployment:-"

I disable Dirsync by PS command Set-MsolDirSyncEnabled -EnableDirsync $False.

After the 72 hour waiting period for the disabling of DirSync, will I be able to add users to existing cloud groups that were created via Dirsync? or is there a command that needs to be run on the group itself to ensure that the group properties are not restrict editing to DirSync ?
