Undefined variable warning

[rickysullivan]

Webstorm throws warnings about unfined variables: "Unresolved variable isEnabled"

const FEATURE_FLAGS = useFeatures();
if (FEATURE_FLAGS.FEATURE_SEND_USER_CODES?.isEnabled) {
    console.log('FEATURE_SEND_USER_CODES is enabled');
}

Is there any way to hide it?

I've added // noinspection JSUnresolvedVariable but that's a pain.
