I am using PowerAutomate Desktop (PAD) to fill an online form in Chrome (https://code.thunderquote.com/PaynowQR/) and then download the resulting file onto my desktop.
This process is part of a flow that then needs to send that file on to the next step in the process. I thus need to get the downloaded file onto OneDrive to then link it and move it along.
My company IT security system is such that I am unable to have the local sync folders for OneDrive on my desktop. Hence, my interaction with OneDrive is via my browser.
Here are my attempts to get the file movement done.

I tried to use the UI interaction option with PAD to try and select the Upload (successful in PAD) and then click on the FILES option (unsuccessful in PAD due to element not being found).
I even tried to do it by drag and drop via PAD but I found the results unreliable due to the need of the mouse to find the exact locations to click and release.
I found this post but the guides it links to are beyond my understanding at the moment.
Any help and direction would be much appreciated.
