@JOduMonT thanks, that's really helpful 🙂
To add the key to the config.js, I added this code below the admin keys part (it can go anywhere though):
supportMailboxPublicKey: [
"~~~YourPublicKeyHere~~~",
],
The snippet in context looks like:
adminKeys: [
//"[cryptpad-user1@my.awesome.website/YZgXQxKR0Rcb6r6CmxHPdAGLVludrAF2lEnkbx1vVOo=]",
],
supportMailboxPublicKey: [
"~~~YourPublicKeyHere~~~",
],
/* =====================
* STORAGE
* ===================== */
And then just restart the app 🙂
