This isn't done (tests and docs) but I wanted to make sure this is valid before doing the additional work.

My reasoning for this is I'd like to allow my kids to use this but I want to limit what features that have access to. This is the first of a few permissions changes (can't edit messages for example) and maybe a new role (LIMITED, RESTRICTED) that includes these by default?

I understand your use case. I'm hesitant to add something like this myself because not allowing deletions is against GDPR and I would generally not like to encourage it. However, I understand the flexibility this offers.

It would make more sense to make DELETE a new Permission and CONVERSATIONS a new PermissionType.

Also, I think you are missing the check on the "Clear all Chats" in the Account Settings Dialog, as well as preventing deletion of archived convos which may be a way to circumvent the current checks (and perhaps ARCHIVE makes sense as another permission, although it may only apply to conversations atm, but this would be out of scope for the current PR)

Hi @danny-avila interesting pov on the GDPR side, but imo having control over your own kids is above any GDPR laws and definitely not where GDPR aims to protect citizens. I would also appreciate having the ability to disable deletion for some accounts.

Also, this should likely go hand-in-hand with anonymous chats, should they ever be implemented. I dont want my kids to be able to use those for the very same reasons.
