Environment details

1. OS type and version: Any

                .setClientId(ClientId.of("123", null))
                .setScopes(Arrays.asList(googleProperties.ads().scopes().split(" ")))
                .setCallbackUri("/customer/google)
                .build();

        return userAuthorizer
                .getAuthorizationUrl(
                        userId,
                        state,
                        URI.create(serverHost),
                        Map.of("prompt", "consent"));

The approval_prompt is not even mentioned in the documentation

Any additional information below

After using it like this we get an error Conflict params: approval_prompt and prompt but there is no way to remove approval_prompt parameter, except manual operation after URL is created.
