Insufficient instructions on ConditionalRender #2480

Describe the bug
Higher-Order Layout Components documentation page mentions using ConditionalRender in quartz.ts to provide custom component rendering conditions. However, unlike, say, instructions on custom Explorer filters in quartz.ts, this bit doesn't explain where specifically the code should be used and what should be imported in order to do so.

To Reproduce
Steps to reproduce the behavior:

1. Navigate to TS Override Instructions in Quartz documentation

Expected behavior
Clear instructions on using ConditionalRender are provided.
