update item permissions for users from external domain
O365 Nintex workflow doesn't support those domains not managed by us. For example, some other organizations have their own O365 accounts so now when those users come on board, we need to create a Security Group in SharePoint group, add the external user into the group after he accepts the invitation. Then we need to add the user to the Security Group. Then re-run the workflow to grant permissions to the user. A lot of manual steps.
