PoE 2 Remote Play Together non-steam

I can't buy PoE 2 on Steam because there's no available in my country.

So i have bought PoE 2 Early Access direct on PoE website.

I have added PoE 2 to Steam but when i open, there's no line "INVITE ANYONE TO PLAY" on Friends List.

I want to play with friend, so any ways for us to play together via Steam Remote Play Together?

Thank you!

I have contact via email and this is what they tell me:
