Yeelight Ceiling Light Auto Off Timer

I got two ceiling lights. They are really great!
I know there is a timer function, but this seems to work only once. How could I set the light to always auto turn off after 5 min f.e.?

use the Automation in Mi Home app

@viettanium sorry, but that doesn‘t seem to be that easy possible from within the automation section. I see only „timer“ option which is a simple time where it will be triggered. Could you submit more detailed instructions, please?
