Additional chat-related features and issues within Microsoft Teams for business
Hi MobileMel2010,
My name is Didi. I'm happy to help you today.
Teams has a 'delegate' feature. However, it only applies to calling such as making and receiving calls on our behalf.
You may check out the linked article for more information:

I also recommend submitting a request for this feature at https://aka.ms/TeamsFeedback or from the Teams app > Help > Suggest a feature.
Best regards,
