auto reply to DMs

Hello, I get a lot of ‘Hello’ Dms with nothing else which is kind of pointless. It would be good to have an auto reply options where i could say “thank for your message. If you are interested in connecting about X YZ get in touch but I am not currently interested in XZY services.” or similar so I am not ignoring people who Dm but also I dont want to reply to people who just say ‘hello’ in their original Dm.
