No I don’t think Phoenix has LNURLs (Lightning address that looks like an email address).

In the end I had my friend set up nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch and she entered her LNURL in the Bitcoin Tips field in nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 profile Settings.

Then since she still has Phoenix wallet, she selected it as the wallet in her Zaps settings to zap out of.
