Does NextAuth refresh access_token automatically?

          })

          const tokens: TokenSet = await response.json()

          if (!response.ok) throw tokens

            // many providers may only allow using a refresh token once.
            refresh_token: tokens.refresh_token ?? token.refresh_token,
