@bhanvimenghani - You can use cypress run instead of cypress open to run in headless mode (without ui) and launch the browser using --browser option. Refer this doc - https://docs.cypress.io/guides/guides/command-line

It would be good to capture the test report and have a script to run the test and process the report and accordingly pass (exit 0) or fail (exit 1) the test. This will enable adding and end-to-end sanity test to github workflow.
