How can i skew a group of objects into a trapezoid?

Hi i have not been able to find a way to make a group of shapes into a single object i can manipulate.

I want to stretch this QR code into a trapezoid shape.

I selected all of the layers and used the "unite shape" tool.

I then tried to manipulate the shape using the anchor points. It was then i realised the "unite shape" tool didnt work how i thought it would.

How can i stretch this shape into a trapezoid?

Is there a way make this into a single object?

("Flatten Artwork" didnt do anything, i also tried making the layers a "Symbol" but was unable to manipulate it using the anchor points)

I am sorry if have missed something obvious. I am new to Illustrator and my Googling and Adobe community searches came up with nothing this time.

Thanks
