Step 6: Right click on .extconfig.json and click on "Create Extension" to see the extension possibilities.

You may now choose to edit the view to add new controls and add the handlers in controller either with new function handles or editing extisting one's. adittionally you can also choose i18n extensions to extend i18n files.

The final folder Structure would look like below. make sure you add ui5-deploy.yaml to add all the BSP, System and TR details. 

Build and Deploy the app with the help of below scripts. (can be added to package.json file)

"build": "ui5 build -a --clean-dest --include-task=generateCachebusterInfo",

"deploy": "npm run build && fiori deploy --config ui5-deploy.yaml && rimraf archive.zip",
