<p>How do I resolve the "Cross-Origin-Opener-Policy policy will prevent the window.closed call" error in my React app? This error appears to be related to the Cross-Origin-Opener-Policy (COOP) policy set on the server. How can I handle this error and ensure that my React app runs properly while respecting the COOP policy restrictions?

<p>So far I've searched and learned that I need to set
Cross-Origin-Opener-Policy: unsafe-none
Cross-Origin-Opener-Policy: same-origin-allow-popups
Cross-Origin-Opener-Policy: same-origin
But I don't know where and how to set it. </p>
