How to use the @wordpress/url.getQueryString function in @wordpress/url

// This ensures URIs with an http protocol have exactly two forward slashes following the protocol.
		if ( startsWith( protocol, 'http' ) && ! /^https?:\/\/[^\/\s]/i.test( trimmedHref ) ) {
			return false;
		}

		const authority = getAuthority( trimmedHref );
		if ( ! isValidAuthority( authority ) ) {
			return false;
		}

		const path = getPath( trimmedHref );
		if ( path && ! isValidPath( path ) ) {
			return false;
		}

		const queryString = getQueryString( trimmedHref );
		if ( queryString && ! isValidQueryString( queryString ) ) {
			return false;
		}

		const fragment = getFragment( trimmedHref );
		if ( fragment && ! isValidFragment( fragment ) ) {
			return false;
		}
	}

	// Validate anchor links.
	if ( startsWith( trimmedHref, '#' ) && ! isValidFragment( trimmedHref ) ) {
		return false;
	}

	return true;
