Add “from (someone)” as WhatsApp?

[Bellisario]

Is there a way to add “from (someone)” as WhatsApp with pwacompat? I’d like to make this effect, but I don’t know if it’s possible and how to do it.
Here is an example:

P.S.: I need this with iOS, so, I don’t care about modify anything on manifest icons (for chrome) but, for example, only add a new key-value pair on my manifest (that pwacompat adds to my iOS icons).
