Currently there is no way to get inventory access of a user in AvatarEditorService. PromptAllowInventoryReadAccess is unresolvable when ran from a plugin and there are no plugin alternatives.
I propose that plugins could have a new permission similar to Script Injection permission which needs to be enabled to give a specific plugin access for reading user’s inventory. This way in plugins we could skip trying to see if we have read access from the service and just instead just manage errors in cases where access hasn’t been given.
