How to use the @angular-devkit/build-angular.executeBrowserBuilder function in @angular-devkit/build-angular

function createTerminal(schema: TerminalSchema, context: BuilderContext): Observable {
  const transforms: Transforms = createTransforms();
  // @ts-ignore
  return executeBrowserBuilder(schema, context, transforms);
}

export function buildCustomWebpackBrowser(
  options: CustomWebpackBrowserSchema,
  context: BuilderContext
): Observable {
  return executeBrowserBuilder(options, context, getTransforms(options, context));
}

export function buildElectron(options: any, context: BuilderContext): Observable {
  return executeBrowserBuilder(options, context, {
    webpackConfiguration: (config) => {
      return { ...config, target: 'electron-renderer' };
    }
  });
}
