Launcher icons appearing behind/in front of a pop-up modal
There may be instances that you will have pop-up modals in your app. When adding a step and a launcher to it, the launcher may place itself behind the modal. You can fix this by adding a z-index within the Launcher panel in the Authoring tool.
Changing the value of the z-index will change the position of the launcher. The increased value will bring it in front of other elements and decreased it will move it back.
There is also a possibility that the position does not change regardless of the value you enter. You may need to check with your front-end developer if there are any CSS from your application that might be overriding the settings of the launcher.
