Add support for Sendinblue chat widget

Hello,

could you please add support for Sendinblue chat widget? (https://www.sendinblue.com/features/chat/)

It is a widget that install inside your website and enable the visitor to chat with the technical / sales support of the site owner.

I saw you already integreted other services by Sendinblue, but not the Chat widget.

Thank a lot,

Matt
