Using "Stays" in modes

Hello- I am creating a new Room Lighting app which is primarily activated by mode changes with separate settings per mode. The app is correctly being activated by mode changes,

My question relates to the "Stays" option in the mode setup. I have this set to 7 minutes. My expectation is that the mode would have to stay in "Day Bright" for 7 minutes before the device settings are activated. However, it is not working this way. The Stays setting appears to have no impact. The devices are activated immediately upon the mode change.

So, what does the "Stays" do in this context, and is there a way to perform "activate when mode stays for 7 minutes"?

There is no "stays" option for Means to Activate in Room Lights. There is such an option in Rule Machine.
