How to deal with security guards who are aggressive and don't understand rules? Digital Sky (Govt website) has GIFT city marked as Green zone (allowed to fly) and I was trying to fly a nano category small drone in public areas and the guard just aggressively came at me and walkie talkied his seniors

The Guard was expecting his seniors to come in the flying squad and break my drone or something but his seniors just said ok and didn't reply to him but he kept disturbing me and was trying to intimidate me I told him in a respectful manner that drone flying is allowed in this area and many people regularly fly in these areas but he was not ready to listen. Anyway I was already lowering my drone when that guy started disturbing me and I had to vacate the area for my safety Do these guys even understand the Digital Sky, Sub 250gm rules, etc?
