How to identify which Google user account any particular push notification is intended for (A13)?

Long story short, my wife has many accounts (against my advisement), and one of them is sending Find Device push notifications that aren't being pinged by either of us. I advised her to check all her GMail accounts for security notices, but she doesn't wish to do so (no idea why). Just to humor her, I'm thinking of taking a look for her but other than sifting through logcat, is there any other method to enumerate/filter this information, whether programmatically or otherwise? She has a OnePlus 10 [TMO][Stock][A13]
