Ask nostr:npub1zcjv4t06jm6tk84nypk8g7q6z8jsra8u8q4kprv08krcpvmskzwqvwam8a. Whatever she's using is probably exactly what you're looking for.

I am using a service that nostr:npub1rv08kght99a7xwckm0qpmzw09m5gwppequgqd8lwu74eakgaavwsp5cjtw told me about that was made by nostr:npub1cmmswlckn82se7f2jeftl6ll4szlc6zzh8hrjyyfm9vm3t2afr7svqlr6f called Zapit.

You can find it at https://www.zapit.live/

It kinda broke recently, and now I have to change out all my old links for new ones, but it's back up and running now!

Anything I have posted in the last week or two should work if you want to see how it works.
