What is the big benefit to using Alby Hub instead of just Alby extension + LNC? That's how I do it and it works fine.

alby hub is quite similar.
but much easier and more lightweight (with that more stable and more universally usable)
also you have more control over app permissions and budget.
but quite similar.
what are the minimum permission requirements for using LNURL (alby account permissions) with my alby hub? Is it just "create invoices"? 
Because it uses your node.
