The simplest way is to pick a Lightning wallet with lightning address support.

For example

Wallet of Satoshi (not available in the U.S.)

Blink (Not available in the U.S.)

Alby (Desktop brower plugin)

Fountain (it's a podcast app, but it comes with a Lightning address you can use)

I just realized how hard it would be if you are in the U.S.....

Super easy for the rest if the qorld though.
