Open Question regarding the Orfeo Toolbox (OTB) extension for QGIS.

QGIS v 3.4.4
Orfeo Toolbox (OTB) v 6.6.1

In the OTB Cookbook for installation everything goes smoothly … until getting to the section for “Activating” the extension in QGIS.  The cookbook states …
Open processing settings
Settings -> Options -> Processing (left panel)
You can see OTB under “Providers”:
• Expand OTB tab
• Tick Activate option
• Set OTB folder. This is location of your OTB installation.
• Set OTB application folder. This is location of your OTB applications. <OTB_FOLDER>/lib/otb/applications
• Click “ok” to save settings and close dialog. If settings are correct, you will have OTB algorithms loaded in Processing toolbox

… things work until the two steps for “Set OTB folder …” and Set OTB application …”  The problem is that there is no way to set the folders.  There is no button or browse capability and clicking on the wording does nothing.  Hence no way to set the folder locations.

The question then is … does anyone have experience with this extension … how to activate the extension … how to set the location of the folders???
