Can't get iOS picker wheel options use appium inspector

Support
1

I use appium-desktop 1.12.1
robotframework 3.1.2
robotfrmework-ride 1.7.1
iPhone 5s 12.3.1(but set capabilities to 12.1, cause my Xcode is old)

there are two options in the selections , truck and trailer, i want to get all options, but only can locate the current select option, is there any way to do this?
