Preview of .xlsx file in the some sharepoint folders

Hi Experts.

I have sharepoint folder structure with 10 sub folders 

Menu Folder  - > 10 folders -> Each folder has files ( .XLSX is of my interest with certain name) 

I did web recording power app to click on each of the 10 folders and adjacent to file click ellipsis (4 dots, vertical?) or Kebab menu with 4 dots ? What menu is that ? 

So I click on the right side on that 4 dots, a menu opens up - > I click down and that is saved 

I repeated this for 10 iterations 

With new powerapp version, while recording, I am not able to click the menu and get to download 

and some folders have file preview thumbnail view .. so the powerapp automation is failing

Please can you help me with the following questions 

1. How do we turn off this thumbnail preview of some folders where file preview is displayed on the top 

2. Is there a to filter the folder for a particular file type and click download so that I use that pattern in automation of powerapp ? 

Thank you very much
