Did you read the getting started guide ?
I think you started the way around and you still don’t get what really is a LN node.
In order to be able to transact on LN, you need to open a bunch channels (inbound and outbound) with your LN node.
Otherwise you are doing it wrong from the beginning.
In that guide about bluewallet, lndhub and umbrel I explained very clearly the difference between a LN node and a lndhub.
