## Description When hmac identity check is enabled according to [this](https://www.chatwoot.com/hc/user-guide/articles/1677587479-how-to-enable-identity-validation-in-chatwoot) I found out, that it checked twice. If `should_verify_hmac? -> true` then hmac checked in `before_action` and we don't need to do it again later. This perfomance related and PR fixes this.
