How to use the @accordproject/cicero-core.Template.fromUrl function in @accordproject/cicero-core

async loadTemplateFromUrl(templateURL) {
        const thisTemplateURL = templateURL;
        this.setState({ loading: true });
        console.log(`Loading template:  ${thisTemplateURL}`);
        let template;
        try {
            template = await Template.fromUrl(thisTemplateURL);
        } catch (error) {
            console.log(`LOAD FAILED! ${error.message}`); // Error!
            this.handleLoadingFailed(error.message);
            return false;
        }
        try {
            const newState = {...this.state};
            newState.templateURL = thisTemplateURL;
            newState.clause = new Clause(template);
            newState.templateName = newState.clause.getTemplate().getMetadata().getName();
            newState.templateVersion = newState.clause.getTemplate().getMetadata().getVersion();
            newState.templateType = newState.clause.getTemplate().getMetadata().getTemplateType();
            newState.package = JSON.stringify(template.getMetadata().getPackageJson(), null, 2);
            newState.grammar = template.getParserManager().getTemplatizedGrammar();
            newState.model = template.getModelManager().getModels();
            newState.logic = template.getScriptManager().getLogic();
