Self-contained build UI5 using WebIDE

[Thanu]

Hi Experts,

I am trying to generate a Self-contained UI5 application via WebIDE. It works when build locally usnig the "ui5 build self-contained --all" command.

This is the package.json

{
"name": "xxxx",
"version": "0.0.1",
"description": "xxx",
"private": true,
"devDependencies": {
"@sap/grunt-sapui5-bestpractice-build": "1.3.62"
},
"scripts": {
"build-self-contained": "ui5 build self-contained -a --clean-dest"
},
"ui5": {
"dependencies": [
"@sap/ui5-builder-webide-extension"
]
}
}

What I am doing wrong or is it not possible to do this from WebIDE?
