.cursorignore is not working

I opened my project in cursor and I need to hide some folders like pycache/
But it’s not working. my .cursorignore file is generated using Cursor itself and placed in the root of project. it contains this:
pycache/

Closed the cursor and re openned and Reloaded window, but nothing happens.

I’m using MacOS 15.3.2
