Email and chat are identical in the modern age. The only difference is the coat of paint. Once chat could send attachments, do replies, persist history, have group chats, it supplanted email and has continued to do so for more than a decade. Chat even ate email's lunch in the one area it had a cultural advantage, conducting business.
I don't want most of my vendors sending me messages on Slack or Teams. If there's an issue that requires attention, please send me a thoughtful email with the relevant information.
