Adding a referrer to the headers for request for assets on the Media Library

[raviz]

You need to create a global middleware 'global::header' (where header is middleware name) and add it in config/middlewares.js

Middleware content ./src/middlewares/header.js

module.exports = (config, { strapi }) => {
    return (context, next) => {
        context.set('referrer-policy', 'origin');
        return next();
    }
}
