${branchName}.my-app.pages.dev and that is great but I don't want to expose any *.pages.dev.app.mydomain.com and I'd like the alpha or beta branch to be accessible at alpha.app.mydomain.com & beta.app.mydomain.com respectively.alpha.app.mydomain.com along side app.mydomain.com under the custom domains section but it resolves as an alias of app.mydomain.com and I fail to see how I can choose what deployment is associated to a specific domain.npx @cloudflare/next-on-pages and deploy using wrangler with the --branch option.
