Implement feedback from KDP reshuffling an Indesign doc

Description

You will receive a book created on Indesign, you need to edit the document to make sure it complies with KDP feedback and once you change the size, you should also adapt the design to be centered, just like a regular book with a nice inside design.
This is the feedback from KDP:
InteriorAdd 0.125" (3.2 mm) to your book's page width and 0.25" (6.4 mm) to the page height to ensure that the images in your manuscript extend beyond the edge of the page. Once you have added the size, extend any images or backgrounds that you want to reach all the way to the edge of the page 0.125” (3.2 mm) beyond the trim line. This prevents manufacturing issues when the file is trimmed to size. See examples PDF page(s) 2 - 3. Watch our video, which explains trim size, margins, and bleed.
I will release funds once KDP reviews and approves because this is my third time paying for little changes and I need to make sure this is the final edit.
You will send it back in Indesign and in PDF ready to upload.
