No, that's fine. It's just a little unclear just from "business owners" whether you personally were in contact with the business owners or not. (I could see checking a business website being considered using the "business owners" as a source, for instance, since it's the business owners who put the information on the website.) It would be clearer to explicitly specify how you were in contact with the business owners, so something like "Telegram conversation with business owners" in this case.
