Can anyone tell me how to ask the user to select a single image from the gallery on the Tizen Gear watch

Currently I am using appcontrol, but it always shows me the gallery and the user can select multiple images, but i want them only to select a single image.

so a click on the image should be enough, I don’t need the images with the checkboxes.

how do I put it in ” single”  selection mode i.s.o “multiple” selection mode. 

example code (js) would we very welcome.

thank you.
