Odd behavior in Excel VBA with KM and BTT

I am trying to set up some stream deck buttons using BTT. Since I’m writing Excel macro’s I want some debugging keys as SD buttons.
One of the is toggling breakpoints (CMD-T). When I set up a stream deck button with just one action ‘press CMD-T’ it doesn’t work in Excel. It just types a ‘t’. Same when I create a KM macro with the same action.
However, when I press CMD-T manually, it works as expected.

Any idea how to fix this?

I assume BTT can run menu items? If so, there is a menu item for Toggle Breakpoint in the Debug menu. If not, use Keyboard Maestro.

Thanks, I will look into it. Sounds like the most obvious thing to do.
