Describe the bug
When we create a tutorial,

Then this Avatar is always showing default value similarly at other pages,
It's because of wrong fetching of user data i.e. it's always null and I came across it while solving issue #1199

To Reproduce
Steps to reproduce the behavior:

1. Create a new tutorial
2. The tutorial Avatar should have shown the alpahbets of user.
3. But Not showing.

Expected behavior
For Codelabz User - it should have showed CU similarly for others.
And in Avatar, name of the user if applicable,
All in all proper fetching of the user data is required.

Additional context
I would like to know the purpose of cl_user_handle collection so if any maintainer can create a thread for it.
