On a private chat, with the new call icon next to the three dots icon (screenshot is not updated), it's only shown "està enregistrant..." losing the context of video, voice message, etc. Maybe we can find a solution that fits better, for example, with the verb "fer" instead of "estar" + "enregistrar".

I have chosen "gravant" as it is more common than the others above. It is the one that everyone would say daily.
