You can do that? Okay, sure! Let's try it.
Apparently, according to Spark, my current address is: 024ff0d07634390efb131904b10a64cf2e3300574b51902d493a360fb522f486fc@p7ppgyr2jzykfo3juuokqwlqe3kvl4ypdysz6v35hzdbeasplm7nvaqd.onion:9735
And in my logs, my pubkey is: 024ff0d07634390efb131904b10a64cf2e3300574b51902d493a360fb522f486fc
I still don't have on-chain funds, yet, and I have to migrate from Spark to Zeus with the CLN-REST plugin. Might try to configure that while traveling in the train. o.o That is, if the wifi there works...
