@Mario A. Hernandez
Thank you for your post!
Based off our Restore a deleted Microsoft 365 group in Azure Active Directory documentation, the only options to restore a deleted group would be through the Azure Portal, AzureAD Admin Center, or PowerShell. From my testing, it doesn't look like the role permission of microsoft.directory/groups/restore
is available to be assigned to custom roles. If you'd like this permission to be added to the permissions list, I'd recommend leveraging our User Voice forum so our engineering team can look into implementing this.
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
