How do I connect server auto start software to playit.gg?

I’m using a software called lazymc GitHub - timvisee/lazymc: 💤 Put your Minecraft server to rest when idle.

so I can save computer resources by shutting server down itself once no player are in the server for few minutes. However I cannot seem to make minecraft recognize that the playit.gg ip is supposed to be directed at my lazymc dummy server where once anyone join, it will boot up the real server.

please help if you know the solution!
