Customizing the top command bar in model driven app form or view buttons - hide button using xrm toolbox.

When I select the solution which was just created as Ribbon Workbench, I get "The solution contains non-entity components (e.g.
I've got only one table in the solution with nothing else...😧

Also, the actual solution which I need to apply the changes in the menu has a lot of components like tables, Flows, web sources and etc. So, when I select either the "Ribbon Workbench" or my actual solution, I am getting the popup saying, "For performance reasons, this solution cannot be loaded:

1. The solution contains Entities that have all their sub-components inclused.
2. The solution contains non-entity components. (e, g., ....)
3. There are more than 3 entities in the solution."

How can I fix this?
