For 27.x version of Emacs you definitely have to build xorg-server package with wayland USE enabled, and Emacs with gtk/lucid. In case if you're using WM, make sure your WM has support for xwayland.
Only Emacs 28 has patches for native Wayland support, so you can try to build emacs-28.0.9999, but I'm not sure if it provides those changes yet.
Otherwise you can use pgtk Emacs fork from here URLﾘﾝｸ(github.com) or here URLﾘﾝｸ(github.com)
