How to use the @hint/utils-network.requestAsync function in @hint/utils-network

        try {
            response.body.content = await requestAsync({

                method: 'GET',
                rejectUnauthorized: false,
                url: resource
            });

                getMessage('canNotGetResource', this.context.language, resource),
                { element, severity: Severity.error }
            );
