How to put different photos (icons) on the same background?

Question

Adobe Photoshop

How to put different photos (icons) on the same background?
there are 100 different icons
there is one background for them
how to do batch processing in Photoshop so that all these different icons are saved on one background?
already broke his head.
I already did this:
1. open the background
2. copy and close the background
3. open the icon
4. launch the action (record)
5. change the size of the field
6. interfere with the background that I copied
7. put the background under the icon
6. run the mage process
and it gives a bunch of some jokes for each action and saves only the background, although the icon is on top of the background
