Add entry to calender / run script with voice

Hi, I want to add entries to the calender for medicine taken. Made a script for that, that just adds an entry ‘Medicine taken’ for this moment. On the dashboard I have button to trigger the script - all that works well.

Now I would like to be able to add the entry / run the script via voice.
Didn’t work to activate the button with voice.
Tried it with input-button but didn’t get it to work either.

Any tipps how to approach this?
