SrtInputNode.removePassphrase() method
Removes a (route, user) access grant from this listener (omit user for the anonymous identity). Removing the LAST grant empties the table, which reopens the listener to every caller unless it was created with SrtInputSettings.requireGrants, when it refuses them all instead.
Signature:
removePassphrase(grant: {
route: string;
user?: string;
}): void;
