1) When setting an application specific button (specifically the "forward" button under the horizontal scroll wheel) to the keyboard shortcut the "type to enter key" input field does not allow any keys other than modifiers. I.e. When trying to type Cmd + C the input field only picks up the Cmd key.
2) When using application specific settings (specifically for Microsoft Teams) the mute/unmute button (mapped to the "back" button under the horizontal scroll wheel) does not work.
