Frameless window latch

I have a 2016 Bighorn with single pane frameless windows. I need to replace the sliding window latches on the windows located on the slide. The tabs broke and will not catch in the open position. Anyone know how to remove the latch for the sliding window. Any help would be appreciated

Here is a link to a place that sells replacement window parts. It may be of some help. [LINK]

Peace
