Looks good to me.

I have two suggestions:

1. It would be better to rename the src/tutorial.tutorial.tsx component to something that clearly reflects its usage as a help-menu-item pushed to the help-menu-slot extension slot. I don't have a suitable name in mind at the moment. @jayasanka-sack, what do you think?

2. I noticed that the stylings related to the help menu list item have been rewritten here, which is redundant. It would be better to keep the stylings within the esm-help-menu-app, so the extension will contain only the text and the internal functionalities.

@Piumal1999
For 2. I've made styling to the extension-slot here, so it wouldn't ruin the styling of newly added extension and can be kept under esm-help-menu-app
