Uptime Kuma and Yunohost API

did someone try to setup Uptime Kuma to monitor statuses of specific services running on yunohost? I tried to use Yunohost API https://my.server.domain/yunohost/api/services and it works well in browser while logged in as admin but reaching that using Uptime Kuma requires authentication cookie (Administration from the API or an external application | Yunohost Documentation) which I can’t simply get and pass to the app. Built-in auth methods of Kuma seems also not to work in that case.
I would be gratefull for any clues.
