Issue with "Swipe up" gesture for last opened app

Message:

Hello, I’m experiencing an issue where the "swipe up from the bottom" gesture to access the last opened app is not working.

• ​Issue: Last app doesn't open when swiping up.

• ​Expected behavior: The most recently used app should appear/open.

• ​Current behavior: The gesture is either ignored or fails to launch the app.

​I am using Niagara Launcher on [ iqoo 12]. Hope this helps!
