Instant sending of mailings from Kommo CRM

Solution: adding a Kommo button to the quick access panel that adds the client's email to the Mailchimp mailings marked by the manager in the Kommo deal.
The use case looks like this:
1. The client calls the office
2. The manager marks in the CRM which services the client is interested in, and clicks the send button
3. During the conversation, the client receives emails with detailed descriptions of the services they are interested in
