I now see it and I have notifications in Amethyst about the zap! I forked the extensions repo and added 0.5.3 and the nwc plugin to the repo lists. 

To update your own you can simply replace the extensions.json file from your server settings with https://github.com/patrickulrich/lnbits-extensions/blob/main/extensions.json

I don't recommend doing this this though because you'll be relying on me to update for future updates to plugins and also trusting I don't feed you bad repos. Instead everyone should fork https://github.com/lnbits/lnbits-extensions and update your extensions.json to what you want included. Then replace the default extensions.json with your own address. 

 i guess this is round 3. just landed on 0.5.4 💣  

 doesn't look to be working on 0.5.4 release for me
