Hello, Has anyone had a chance to complete Platform Developer I Certification Maintenance  module for Winter '20 ?

I am having hard time with the second submodule Hands-on Challenge, Based on the question I have create a Lightning web component with name 'myComponent' and also added a lightning card to this component. However when trying to add a new custom tab to this component, I am unable to see the 'Lightning component tabs' related list under setup> 'Tabs' section. Not sure if I am missing anything, appreciate any help. Thanks !
