How do I get my videos to reach my audience?

I upload videos inside a "roblox" game yes I understand that may be slightly childish but that is beside the point

I know this specific game has a large audience alot of videos get hundreds or thousands of likes and I struggle to get 5

I know tiktok isn't pushing it to the right audience I live in turkey but I have a British sim card the game doesn't have a good turkish audience at all im curious I heard somewhere if I put another country's sim card in my phone then open a vpn to that country it supposedly pushes my videos to that country is that a true method worth trying?

Or is there another way that may be better the region in my tiktok account does specify "turkiye"

Thank-you
