I have a DM currently telling me that I need to spend an action each round in order to use it? But my read of it doesnt say that... so I dont know whether I am right or wrong.
The effect just lasts for 1 minute unless you are incapacitated or die, you don't have to maintain concentration and it doesn't say anything about using an action on subsequent turns.
Also given that the effect happens at the END of a character's turn, then it has nothing to do with your action.
As stated in the title?

I wouldn't think so either.

Your DM is wrong on this one. You only need to spend the action when you initially use the ability.
