We will use below kendo code to add custom button, this custom button will use to upload document to one drive location::
<Editor
tools={[
[Bold, Italic, Underline, Strikethrough]
]}
contentStyle={{ height: 300 }}
onMount={this.state.onBlur}
defaultContent={this.state.value}
How can I add custom button in the kendo's editor of SPFx react project?
