Macro to populate username and password in 3rd party add-in pop up

[MurrayBarn]

Hi All

I use a 3rd party add-in in Excel and every time I start Excel, I have to manually add the password etc. I tried recording the process but the macro recorder does not recognise the login pop up. Is there any way I can do this so I can create a shortcut button that will launch the add-in, populate username and password on the pop up and click OK?

A few things come to mind that I have a little familiarity with:
1. Automate it with Power Automate Desktop.
2. Automate it with some other scripting/automation tool like autoHotkey (probably more complex)
3. If possible, modify the addin (may or may not be possible depending on what the addin is and if it is open source or not).
