Svelte Kit Environment vars pages

I am using @auth/svelte it use environment vars for AUTH_TRUST_HOST which needs to be true and some google secrets. These are picked up in dev locally but not getting in production. I have tried declaring them in wrangler.toml: [vars] AUTH_TRUST_HOST = true and also in the dashboard: [see image] But either way platform.env.AUTH_TRUST_HOST is null and I get errors complaining it needs to be true. How can I set enviornment variables so they get picked up by sveltekit on cloudflare?
