If we add more number of files to Microsoft teams then.. the file navigation goes up while we scroll down in search of a file and if we need to go back to the previous folder..we have to scroll up again and click on folder to redirect to a specific folder...
Instead docking the file navigation history to the top leads to better User-Experience in files tab.
file navigation history
Also a add a "back" button to go back to the previous folder from a document opened in native application would be appropriate which is currently missing. so that it would be easy to use.
