Homey Google Assistant IFTTT Delay

Hi Community

I am using Homey in combination with Google Assistant to trigger flows over IFTTT. I have a flow to close my windows. It works to trigger the flow like „hey google, close windows“. now i try to include a random delay before closing the window.
Example: „Hey Google, close windows in x minutes“. IFTTT offers me to include numeric value in the command but i cannot figure out how to pass the variable (x Minutes) to my homey flow. Did anyone successfully create something like that?

Any help is appreciated :blush:
