Switcher_kis integration add support for turn on with timer minutes

Currently the integration is only able to turn it on of off.
Could we have the option to turn on the Switcher with a set timer similar to how we can activate it with the switcher app, in 15 minutes intervals?

Are you asking for something else than the existing services, switcher_kis.set_auto_off and switcher_kis.turn_on_with_timer?

Sorry. That is correct. I missed that part.
I am very new here and did not notice the service section.
Could you help me with an example how to code that or in the HA interface so I would have a menu for this option?
