Custom component not appearing under My Components

[jaquilio]

I followed the instructions at https://doc.qt.io/qtdesignstudio/quick-components-creating.html to create a custom component named ModeSelector which I want to use in my UI. I see that a file named ModeSelector.ui.qml is present in the folder I created to store such custom components. What do I need to do to make these custom components appear under "My Components" in Qt Design Studio?

A Component will not appear if you are currently inside that component.
e.g. if you have components A and B then component B will be visible if you are editing component A and vice versa. Any component with a capitalized name, that is derived from Item and does not contain syntax errors should be visible.
