SDK for Gl.Inet router UI

Hi! Is there any SDK for developing custom pages for Gl.Inet router firmware? E.g. I use AdGuard VPN on all my devices. There is an opkg that works fine, but it only works via command line that’s unusable if you’re not a power user. I recommend your routers to my friends, but in the case of AdGuard that one of few that works in Russia, it’s impossible to configure it without commandline on Gl.Inet. I’d try to develop a custom page for AdGuard, but I didn’t find any approaches.

Unfortunately, there isn't at the moment.
