I neeedd this type.

https://github.com/puppeteer/puppeteer/blob/main/src/common/PuppeteerViewport.ts

but it seems not to be exported in node_modules/puppeteer/lib/types.d.ts:24210

declare interface Viewport {
    width: number;
    height: number;
    deviceScaleFactor?: number;
    isMobile?: boolean;
    isLandscape?: boolean;
    hasTouch?: boolean;
}
