I doubt it will work, even for China it seems you need to pay an annual fee for DJI service to make it work, I guess it needs to go through some nation wide servers or something.
Another question to me is if it works when using RC Pro only or also with the standard controler (RCN1), in the website you can read it supports
Mavic 3,
Mavic 3 Cine and RC Pro, it doesn't say anything about RCN1, but maybe that is because in the case of using RCN1, the dongle actually doesn't need to connect to the controler, but to the phone.
