How to use env variable with wrangler preview?

So i add a secret with wrangler secret put and use it. it works

however, if i do wrangler preview, the secret is not there hence it will throw an exception

how do i use secret with preview command?

I believe it is not possible as it is encrypted at cloudflare edge.
does it work with non-encrypted vars set on wrangler.toml?

yeah it does. but i don’t wanna put it there since it’s secret.
