Sorry about the delayed response, I have been traveling for the holidays and am seemed to have caught a cold in the process.
Here's a screenshot, I have highlighted the menu with a green rectangle:

My SD card is rather old and started malfunctioning recently so I no longer use it with my device. If I did have it or other compatible external storage connected and tapped that menu, it would bring up the options to 'Scan for files' or change between 'Storages'.
I hope this clears things up.
Best Regards,
Adam @Mixvibes
