next-auth@beta config with async/await

[dainvinc]

I'm using next-auth@beta as my default auth library and I'd like to pass in some decrypted values to my custom provider that I'm using. How can I achieve this as it looks like async/await is not supported by next-auth@beta.

auth.ts file:

export const { handlers, signIn, signOut, auth } = NextAuth({ debug: true, secret: <authSecret>, providers: [ { id: 'custom', name: 'custom', type: 'oidc', issuer: <authIssuer>, ...otherConfig } ] });

How can I pass these resolve authSecret and authIssuer promises before passing them on to the NextAuth config.

In my .env file authIssuer and authSecret are encrypted values. And, I want to decrypt these values before I send it to NextAuth.
