Object.values() is part of ES2017, and the compile error you are getting is because you need to configure TS to use the ES2017 library. You are probably using ES6 or ES5 library in your current TS configuration.
Solution: use es2017 or es2017.object in your --lib compiler option.
For example, using tsconfig.json:
"compilerOptions": {
"lib": ["es2017", "dom"]
}
Note that targeting ES2017 with TypeScript does not emit polyfills in the browser for ES2017 (meaning the above solves your compile error, but you can still encounter a runtime error because the browser doesn't implement ES2017 Object.values), it's up to you to polyfill your project code yourself if you want. And since Object.values is not yet well supported by all browsers (at the time of this writing) you definitely want a polyfill: core-js will do the job.
