This worked! From Matt below "Just start a "Meet Now" (from the Calendar section located in the left sidebar) meeting with yourself and then type something in the chat and then close the meeting and the chat will continue to be in your chat history. You've just now created your own personal chat.
MS please make this easier by just adding the ability to start a new message with yourself. TY for your time.
