Extract the minutes just one digit at a time.

now it directly skips to "press to start timer" after "press to show recipe". how can i fix that

Don't set Button_Recipe invisible?

now its like this but i want the timer button to only appear when the step contains “minute” how can i fix it

You need an if/then step testing if the current recipe step contains 'minute', early in your logic.
