Can't select file from OneDrive - seeing files from another computer drive

[PowerWhy]

Hello,

When I click on the circled "Show Picker" I can only see files from my company's shared drive, not my OneDrive. Please does anyone know why that would be / how I can fix it?

Many thanks,

CW

It seems I selected "Excel Online (Business)" when I should have selected "Excel Online (OneDrive)".
