WeTransfer application

Hello all, WeTransfer has a desktop application on mac. When the application is open, there is an icon on top of the screen (like bluetooth icon, wifi…). To transfer files, you simply drag your files on the WeTransfer icon on top and the upload start.

Is there any way to address that WeTranscon Icon in a script so that my files get uploaded without doing it manually? the script is done, I just need to know if I can access that (i guess Temporary folder that WeTransfer is using)

Thank you
