It seems there is no way to access external storage (i.e., an SD Card) in the document browser. Only folders / files of the internal (emulated) sdcard are shown.
I confirm this.
Had to copy documents from SD to internal memory.

Just checked with version 126.96.36.199.alpha0+ Build ID f6a74ce, running on an LG4 with Android 6.0. Selecting "External SD" as the document source results in a disappointing "Invalid root file. Check your configuration." message on a mauve background flashing up.
I suspect that the issue is with Android 6.0
@rag Have you navigated to the settings menu and set the root directory of your external SD card?
The sources of error could either be that, or as you have mentioned, Android 6.0
I am unable to help for this as I am still unable to get the Android 6.0 emulator working with LO Android. Do hope that someone else can step in to lend a hand. :)
I think this mab is solved already.
My version is 188.8.131.52.alpha0+.
