Can't modify the mode and language

[Zacle]

I've tried several time to modify the initial theme and language but without success. Here's my code. Any help would be appreciated render() { return (<> <ReactAce mode={this.props.language} theme={this.props.them} name="code" style={{width: "100%", height: "500px", fontSize: "12px"}} editorProps={{$blockScrolling: Infinity}} onLoad={(editor) => { editor.focus(); editor.getSession().setUseWrapMode(true); }} ref={instance => { this.ace = instance; }} /> </>); }
