Removal of Bumper Air Knives plastic pieces

So,
I want to remove the air knives on the front bumper of my GLC43.
I see that there are these plastic circle items that seem to be surrounded by a rubber piece.
I have two questions...to remove the black plastic piece, do I need to remove these plastic parts that I've circled below?
And how do I remove them?
I stuck a pick along the side of the rubber part and I can't see that this can be removed from the front.
Any advice?

The round one is the parking sensor. They push in from the back of the bumper. Don’t remove them, no need.
Removing the air fins will leave lines in the air vents like something is missing.
The vents have clips in the back that make them easier to remove. You could possibly push them back but putting them back on will be difficult without removing the bumper.
