Breaks builtin handling in Slack

[nhardy]

Slack appears to handle the side buttons itself, but when enabling this tweak this functionality in Slack appears to be broken.
Possibly related to #76

I added it to ignored apps on my fork. (You need Xcode for installing it and you will need to remove it from Accessibility permissions then restart the app to add it again because the install process builds it to run locally, so the code signature changes from the previous version)

brew install --cask cyberbeni/brews/sensiblesidebuttons-fork
