Location on Fold For Covid world map


I’m just wondering how one gets ones location to appear on the Google Maps world map on the Fold For Covid homepage? I’ve had 2 Raspberry Pis chugging away for a while but my location doesn’t appear on the map. I realise that my contribution may not be earth shattering as they have only racked up 3360 credits between them so far, but I was still hoping my location might appear on the map. I appreciate that my request may appear both trivial and vain (which it is!), but it would give my kids a buzz to be able to see that their old man is doing his bit for the cause.
