Open automate flow with bixby key

I made an automate flow to start record in until I switch screen off, I made it to be my personal quick recorder.

I want to use bixby key to trigger the flow when I click it but I can't do it.

What I tried so far..

I used an app called 'Home Launcher' I made it to open the flow when I long press home key instead of google assistant. But when I try bixby key it open the launcher and then I have to click on the flow.

What I want..

An app to open a short cut without any interface when I open the app for the first time it make me choose what to open and then every time I click the app it open the flow immediately.

What the use of that..

When I want to record a fast note I open the phone and click bixby key then automate will start recording when I done I lock the phone to make the flow stop and save the voice note.

Here is the flow I use..

I made it.

The simple answer.

1. I used an app called Mute, all it does is to mute phone.
2. Made bixby key open the Mute app.
3. Made a flow to watch when phone is mute to start recording.
4. Made a fork in the flow to watch when phone is unmutes to stop and save the recorded note.

How it works.

1. When I press bixby key it mute phone,
2. Then automate start record,
3. When I press bixby key again the phone is unmuted,
4. Automate stop recording.

And finally I made my samsung flagship a very assume voice note recorder.

Thanks for all who tried to help.

Good luck everyone.
