Refresh Token without access first time

Question

My app uses long-lived tokens.
I'm migrating the app to use the refresh token.
I generate the url correctly and retrieve the refresh token that I use for subsequent connections.
But to generate the refresh token, even if I pass my apikey, I am prompted to log in to dropbox. is it possible to avoid?

No, whether you're using the OAuth flow to request a long-lived access token or a short-lived access token/optional refresh token, the user needs to manually authorize the app, and they need to be logged in to Dropbox to do so. If they are not already logged in, they will be prompted to log in before they can choose to authorize the app to access their account.
