Change settings viewer for external software application

Hello,

My accounting software Exact Online is using "Acrobat Reader" for showing documents. However when i want

to enter a new invoice by uploading a pdf, the viewer is not presenting it fullscreen. Please find among printscreen.

How can i change the settings within Acrobat Reading to read modus, like it's working properly in external software applications?

I am looking forward to your responses.

Regards, Barry
