Someone was already working on this (#511). It does look like that effort stalled, but could you confirm with them please before we proceed with this new PR, out of politeness.

It would be good if you could communicate what you are intending to work on before you start doing it, that will help avoid this sort of situation.

I asked him and I'm waiting for his response.

Yes. I should did more than assigning issue (#508) to myself.

Let's give it 3 days to wait for an answer. In the meantime, can you please close this PR and re-open after that time (I assume you have properly self-reviewed, if not please do that before re-opening).
