Only if you want DM notifications. Your DMs are now so private that even our Push Notification server cannot see them. So, if you want them, you need an opening, but everyone else will also see your events.
I disabled Amethyst's notifications because I'm using Pokey which is hooked to my private inbox relays. I haven't had any DMs since I setup Pokey, but I'm assuming that it will be able to deliver DM notifications. Could you send me a DM to test that?
I don't know if Pokey is already AUTHing with your Amber key. That will be required to see your DMs.
I didn't get a Pokey notification for your DM, so I'll add nos.lol as you suggested. Hopefully that will trigger a notification on DM.
Maybe a future version of Pokey will be able to auth via Amber to allow reading the DM relays.
