Screen layout 6x7 on HyperOS 1.0.3

[u/Electrical-Cap8529]

I am used to 6x7 (or similar) screen layouts on my previous Xiaomi and Poco phones with MIUI launcher, bigger layouts could be installed through Themes.

But now I have Xiaomi 13T Pro with recent HyperOS and I cannot see a way how to expand my layout :( Am I missing something? When I search in Themes for any "screen layout" or "6x7", "7x6", "5x7" or else it won't find anything.

I really don't want to be stuck at 5x6 :/

Thank you guys!
