I would like to implement a chat system like this on my site: https://www.youwe.nl/en/
- With a admin panel to manage all conversations easily (preferably in the webapplication on my phone with push messages.)
- Full chat history
- leave message option, when not online (send mail/push message)
- Sound notifications on new messages and or push messages
- Works on all devices
- Who can make something like this for me
