addAction method from client/views/room/lib/Toolbox/index.tsx not present since 6.4.0

Description:

Prior to version 6.4.0 the addAction method was exported in /client/views/room/lib/Toolbox/index.tsx. This method allowed to add more buttons into the room header toolbox. But this file is not present anymore.

Steps to reproduce:

1. Have a custom JS script with this import: const { addAction } = require('/client/views/room/lib/Toolbox/index.tsx');
2. Open a room
3. JS error appears in the developers console

Expected behavior:

The file exists, the method can be instantied and called properly.

Actual behavior:

url_common.js:80 Uncaught Error: Cannot find module '/client/views/room/lib/Toolbox/index.tsx'

Additional context

I'm trying to search where this method has been moved to... But no clue where it has gone.

Relevant logs:

Start by checking the repository history for client/views/room/lib/Toolbox/index.tsx and tracing the current room header toolbox entry point. Confirm where addAction went or whether the old import path needs compatibility support; done means the reported custom import can instantiate and call the method without the module error.
