@huihee62 thank you for the discussion, you should be able to extend ElectronMainApplication and pass your own minWidth and minHeight options to getDefaultOptions.

The default implementation uses the following values:

            protected getDefaultOptions(): TheiaBrowserWindowOptions {
                return {
                    show: false,
                    title: this.config.applicationName,
                    minWidth: 200,
                    minHeight: 120,
                    webPreferences: {
                        // `global` is undefined when `true`.
                        contextIsolation: true,
                        sandbox: false,
                        nodeIntegration: false,
                        // Setting the following option to `true` causes some features to break, somehow.
                        // Issue: https://github.com/eclipse-theia/theia/issues/8577
                        nodeIntegrationInWorker: false,
                        preload: path.resolve(this.globals.THEIA_APP_PROJECT_PATH, 'lib', 'frontend', 'preload.js').toString()
                    },
                    ...this.config.electron?.windowOptions || {},
                };
            }
