I want to create a custom toolbar to add html

[sanjitbauli]

addVideo = (videoid, height, width) => {
        const { editorState, onChange } = this.props;
        const HTMLToInsert = this.videoPlayer(videoid);
        console.log(HTMLToInsert, HTMLToInsert);
        const contentState = Modifier.replaceText(
            editorState.getCurrentContent(),
            editorState.getSelection(),
            convertFromHTML(HTMLToInsert),
            editorState.getCurrentInlineStyle(),
        );
        console.log("contentState",contentState);
        onChange(EditorState.push(editorState, contentState, 'insert-fragment'));
        this.doCollapse();
    };
    videoPlayer(video_id'){
       return '<div id="ktp1test" data-widget="videoplayer" data-videoid="'+video_id+'" data-videotype="kaltura"><a href="">Watch the video</a></div>'
    }

It is showing RAW HTML code as output.
