does this help: https://github.com/dolcalmi/lnurl-pay/issues/3#issuecomment-1071237501 - is this releated?

I just tested this again and I think we should make it easier to use in the browser. Many apps are client side apps. seems that the bech32 depends on the buffer but I think we could refactor that to get rid of it.

yep, also just updated the dependencies and axios force me to add a lot of fallbacks... I will try to find some time this month but PRs are wellcome
