Have a look to Urmet 1750/1 - #19 by Dennis_Vermeulen : So far it seems that these models, including yours are not supported on nuki opener.
Sorry for you,
Best regards
PS one of the post suggests switchbot as an alternative, it might helps except you couldn’t share it with Airbnb directly, at least it’s a possibility.
PPS contact the nuki support directly they were quite helpfull in my case.
