How to hide the view and exit (back) button in the download page

Hi there,
i have a grid whit a nested grid that shows a grid in WORD view. the user sees the grid and in the nested grid the download button to see a generated document.

i want to hide the back or exit? button in the download view and if possible also the view button (don’t know what the function of that is in combination with a word file)

any suggestions?
