I am planning to give access to my workflow to only a few users within a collection, not all the users in that collection.
To achieve this requirement, i am planning to get username using "__cloud:UserId", and validate this username using predefined user list which available in a static file. But when I use "__cloud:UserId", I am not getting any username in my gallery. I have attached the workflow to get a username for reference.
Also, Please suggest me if there is any better solution for this scenario.
