Uploading images with Katalon Recorder

Guys, may I request your support for uploading image type question.
I do not have any developer knowledge and using Katalon recorder on chrome to add product to ecommerce site.
I need to add images, 10 images per product with Katalon recorder.
I read below thread, but I am still not able to make it work.
The button for opening fuile broowser to choose images in my pc is clickable by Katalon recorder.
But I am not able to select the images.

I am pasting the results for the Chrome inspect element when I copy element, html or the selector field from inspect element dialogue box.
From the CSS window, “button” is active when I hover on the button on page. Other CSS selectors are grayed out.

I am also attaching 2 images, 1 for the inspect element screenshot with the button.
Another with the images I want to upload.
Can you kindly guide me how to proceed in this situation.

Copy result from Chrome inspect element:

  1. element:
    Select Image

  2. HTML:
    Select image

  3. Selector:
    #main > form > section:nth-child(1) > div > div.FileUploader__InputContainer-sc-f66k10-3.cCfDjr > mer-button > button
