add a button to copy image to clipboard

When using Plotly in Jupyter (Either with Python or Julia) I appreciate the interactivity of Plotly.
It is a great experience compared to Matplotlib.

Yet I miss the ability to copy the image into clipboard in a click.
I'd like to have a button, just like the Download PNG button which instead of downloading the file will copy the bitmap into the clipboard.

It seems users are looking for such feature, though for now they try creating a bypass:

• https://github.com/plotly/plotly.js/issues/6060.
• https://github.com/plotly/plotly.py/issues/2114.

I found that R users are also interested in this feature: https://stackoverflow.com/questions/72323149.

Any chance to have this feature added built in?

まず、plotly.js にある既存の Download PNG ボタンの実装を見つけ、ビットマップの生成方法を確認します。画像をクリップボードにコピーするためにブラウザーと Jupyter で必要となる動作を定義し、サポート対象の操作に対するカバレッジを追加して、新しいボタンが既存のダウンロードコントロールと併用できることを確認します。
