How you guys did a lighting address without Wallet of satoshi???

I was asked if I keep my emergency reserve in bitcoin. Well... I used to keep part of the emergency in bitcoin, but during the pandemic, after I got pregnant, they said that my work was not essential and I had to use all the emergency reserve. Including the bitcoin part. That saved me, but I don't have the courage to sell what's left to make an emergency reserve in Fiat right now... So, technically, I don't have an emergency reserve.

I had to create a lighting address with the Wallet of satoshi... I couldn't do that using the muun wallet... Is it possible to have a lighting address with the muun?
