Automate certificate uploads into Plesk (using Selenium-IDE) not working

I would like to automate the uploading of renewed certificates into different Plesk environments, by setting up a Selenium-IDE script. All is working so far, except for the upload part of the script. I understand that I somehow need to send the file to the input field, but would not know how to target that input field without the id -- it has no id!

This is what the page looks like; it is the middle "Upload .pem file" button that one would use to upload the file.

The code of the middle section "Upload .pem file" is:

<div class="ext-sslit-certificate-dropzone" style="position: relative;" multiply="false" aria-disabled="false">
  <button class="pul-button" type="button" data-test-id="ext-sslit__certificate-upload-button">
    <span class="pul-button__inner">
      <span>
        <span>Upload .pem file</span>
      </span>
    </span>
  </button>
  <input accept=".pem" type="file" 
    style="position: absolute; inset: 0px; opacity: 0.00001; pointer-events: none;" 
    multiple="" autocomplete="off">
</div>

Maybe there is a way to target the accept=".pem" section, which is unique on the page.

Clicking on the button records:

command: click 
target:  css=.ext-sslit-certificate-dropzone .pul-button__inner > span > span

Selecting my .pem file records:

command: type
target:  css=.ext-sslit-certificate-dropzone
value:   C:\fakepath\wildcard___my_domain_name.pem

But playing it back it is stuck and not inserting the text into the "brows to file window" of the file I selected.

The file gets posted to a URL:

https://plesk.cc:8443/modules/sslit/index.php/index/upload/

I tired different things, but can't get it to work.

(And, why is my file location getting renamed with C:\fakepath\?)

I found that UI.Vision offers XType functionality, but got stuck there just as much; link to my post on UI.Vision's support forum ...

I got it working using UI.Vision.
