AFO Workbook downloaded from BI Launchpad opens a new blank browser tab

Hi experts,

we have published AFO workbooks into BI Launchpad. Users click on the workbook in BI Launchpad folder and it's correctly downloaded and automatically opened by AFO (version 2.8).

However, the download of the workbook opens a blank browser tab.

Since this is an unpleasant behavior for users, how can we avoid the blank browser tab?
