Code To Reproduce Issue [ Good To Have ]

range_knob = node.find_element_by_class_name('range-knob')
action_chains = ActionChains(self.driver_)
action_chains.click_and_hold(range_knob).move_by_offset(xoffset, yoffset).release().perform()

You could call ActionChains api with x/y coordinate (instead of an element) after switching the context with “NATIVE_APP”

If you want to perform native touch actions on web elements, you will also need to map the web coordinate space to the native coordinate space, as they are not the same. You can do this by getting the rect of the WebView element and using it to relative the web coordinates reported inside the webview.
