icons for less popular social-media sites?

Thank you for FTH4, a design easy on the eyes. Per https://docs.toastmastersclubs.org/doc/item/social-links/ (couldn't find the info in https://support.toastmastersclubs.org/?)
"The icon is chosen for you....Anything it does not recognise gets a plain globe...".

1. Is there a minimum number of social-media-site visitors currently needed before FTH4 adds the icon? Our club uses 3 sites whose icon is currently a globe — Bluesky (~46 million registered users), Yelp (~75 million), and Nextdoor (~110 million). In comparison, Instagram = 3 billion users.

2. In FTH3 we could add the icons ourselves. Any estimated time before FTH4 includes this?

3. If no addable icons, then could we eventually add the social-link name as text, like Bluessky, etc.?

Thank you. HarryHolland club #2943
