Setup btcpayserver-docker with the opt-add-ltcmweb
fragment.
Install the plugin (or restart BTCPayServer if already installed).
Add MWEB View Keys to Litecoin MWEB Wallet settings in BTCPayServer admin.
They can be retrieved using Electrum MWEB (release-9 and later).
Nope. I've gone the same way, but only the Litecoin, not the MWEB Node, is working. ;/ But additionally, I decided to activate the pruning of the LTC node. But it's impossible, that I have to run a full LTC node for running MWEB.
That's what the server says;
LTC MWEB
Node available: False
