Create a reference Tab for Assets and Shots

Hi, I’m trying to create a new reference tab in Shotgrid assets and Shots pages and need some help. Is there any documentation about how to do that on the new shot grid?

We are looking to have our multiple reference images accessible for artists and Supervisors on the Assets and Shots pages.
We are also looking to have those linked and available as a comparison in the shot grid created for comparison.

I have tried using this as help,

but for some reason, the shot grid won’t let me create a new tab, only duplicating the ones there. Also, I can’t find the reference image type in the tabs option.

I appreciate any help you can provide.
