Arrive at home -> start music with Alexa

Hi community,

I have a Nuki SmartLock, and I have Alexa (Echo Dot) at home.
I would like to create some kind of routine which does the following: I arrive at home, auto unlock opens my home door, and this triggers Alexa by playing a predefined playlist.

I tried to do it with IFTTT, but the Alexa service is not available in the “then” clause (Alexa can only trigger something else). I also tried it with a Alexa routine (in the Alexa app), but Nuki is not supported in the “When this happens” part of the routine.

Would anyone else know how to achieve that (without setting up e.g. OpenHAB or other SmartHome environments)?
