Chrome Extension for CRM integration with Gmail

I have a CRM for small businesses. I want to integrate it with Gmail.

This will need sections to accept inputs and responding to them in composing an email.

– text input
– Notion like command
– Action button

I will look forward working with good people here on freelancer
