Is there a way to make a photo seamless?

[bonvo4]

I've seen tutorials that explain how to create a seamless pattern when starting with a blank canvas and having the ability to move objects around.  What I'm curious about is if there is a way in Affinity Photo or Affinity Designer that would allow me take an existing photo and make it seamless so that the seams will come together on the left and right.  I'll attach a photo of an example.  In this example, I would like the palm trees and water to line up better, but I wasn't sure that this was something that was even possible or not.

Thanks!

It would work better if you add isolated leaf(s) plus the missing trunk, placed at the / exactly divided by the image edges.

For the sand it will be easier to entirely replace it with a less diagonal structure near the edges. (or, if you are attached to this particular image, copy the middle part of the sand and scale/stretch it to the edges to cover the diagonal structure).

You can use the affine tool, shift by 50 % in x axis, use patch tool and inpainting to hide seam, shift back, create pattern layer from selection.
