Openconnect Plugin ist not available

Hi,
Im using GL-ACT1800 as a travel router and for working out of office.

I would like to configure and use cisco AnyConnect VPN on the router, but unfortunately the OpenConnect Plugin seems to be unavailable. Is there anyway to get OpenConnect installed on GL-AXT1800?

Thank you and best regards!

Received, will try to compile this plugin and put it in repo if it works in the op23.05
