Voice Messages same as Whatsapp on chats

Hi,
Voice messages on chats would add an extra to the existent system:
The user would be able to send voice messages and also the agent.
Ideally will also include cam + audio recording videos.

That would be really useful for requesting testimonials and also for other uses such as provide asynchrony coaching for language schools (covid has shown us that we can improve in many ways so this would be one).

Thanks for considering this.
Cheers!
