Not able to create/apply custom theme to "Agent Workspace" experience

[Narasinhak]

I have created a UI Builder experienece using "Agent workspace app shell" experience.

Its default theme is set to "Polaris".

I am not able to change the theme to something other theme. Theme selection is disabled.

How to change the theme here?

If you've created a new configurable workspace and have the Next Experience UI turned on, it will open in the unified navigation and inherit whatever the instance theme is. There is no easy, configurable way to theme workspaces differently with the next experience ui turned on.

Does that mean that I cannot have a different logo in the top left corner for Agent Workspace for HR Case Management vs vanilla Agent Workspace or anywhere else in the backend? They all need to be the same logo in the banner?

That's correct. The configurable workspaces open inside the unified navigation shell and the header menu, logo, etc. all live in that outer shell.
