Show Window Switcher does not show apps created with Brave's save shortcut -> open as window

As mentioned in the subject, I have a few applications created with Brave (Chromium) that run in their own windows similar to SSBs. They were created using the option to 'save shortcut' and 'open as window'. None of these apps show in window switcher though all other windows of Brave do. These apps also show using the normal cmd-tab so I'm not sure what's going on with BTT.

Device information:

  • Type of Mac: MacBook Pro M1
  • macOS version: 12.5.1 Monterey
  • BetterTouchTool version: 3.870

I had set this up to use cmd-tab as a replacement to the system shortcut but have now set it to a different shortcut so that I can still use cmd-tab to get to the missing apps.
