how to test and write test cases for reactjs app with protractor?

okay I have been trying to test my own react app with protractor but I don't know the correct syntax of test cases. I searched few things like await browser.waitForAngularEnabled(false); command is useful but still don't know how to write test cases for react app. tutorials are available for angular only, like for example how to click on certain button, how to write in input box, how to verify test result, how to match values, how get title etc kindly guide me in this because I need protractor for it. Thank you in advance.
