Send Multicast downlink messages using the Python SDK and Chirpstack API

Hi,

Does anyone have a example for sending Multicast-Downlink messages using the Python SDK and Chirpstack API?
I have seen this one: Python examples - ChirpStack open-source LoRaWAN® Network Server
which works nice with my setup for normal device downlinks but I can’t find a example for sending downlinks with a multicast group (in the application server I added a multicast group and added two devices into this group).

I checked the locahlhost http://localhost:8080/api but I don’t get how to implement these functions in python or javascript…

best regards
Corsin
