REST_COMMAND: Cousin's Shelly device shared to my Shelly account / controlled with MY Home assistant

Third party integrations
1

Hello,
I have Home Assistant with Nabu Casa, I also have some shelly devices integrated into it from my Shelly account. Me and My whole family we use Android devices.

On the other end, my cousin uses just Shelly Cloud and he uses iOS devices, so he has his controls via Shelly App & iOS shortcuts. Lately he connected his garage gates with Shelly 1.
He shared those to my Shelly account and I can control them from there.

And here is my question:
We need him to share the gate shortcuts with us so we can get our cars into his garage when we visit him.
Any advice how to do this without the use of Tasker? The perfect scenario if I can get those into my Home assistant and it will be available to all my household at once.

How can I do that?

Thanks in advance

Hi,
Is there any straight forward way to get this working?

I spent hours with no luck.

Using the ARC ‘Advanced Rest Client’ app it works, but not via Home Assistant.
Any advice?

rest_command:
  test1:
    url: https://<Shelly Server>/device/relay/control/
    method: POST

I did check those topics with no luck. What am I missing?
