Action Sheets - Where?

I am just starting Ionic and Cordova, so I don’t know much.
Where is the Action Sheet’s code in the tutorial starter template (When I Click the “Toggle Menu” button or the Menu button in the top left corner, it opens up an Action Sheet, in this case, the menu.)? My best guess is the app.component.ts TypeScript file.

Check this.

Up to you to look for it as you’ve not given/posted any code.

OK. I think I found it. It was the menuToggle function that opens up the menu, or action sheet coming from the left. facepalm
