How to open a URL in SteamVR's web browser?

I have a SteamVR game and a button in my UMG main menu that I’d like to link to a Discord invite. Currently I am just using the “Launch URL” blueprint node, and this works, but it opens the link in Chrome and there is zero feedback in-game about what happened. I’ve seen games before that open links in SteamVR’s web browser, but I cannot for the life of me find any information about how to do this.

Anybody know how to do this?

Figured it out. For anyone looking in the future:

void UTabletUserWidget::OpenWebpage(FString URL) {
	if (SteamFriends()) {
		SteamFriends()->ActivateGameOverlayToWebPage(TCHAR_TO_ANSI(*URL));
	}
}

Of course after doing this I found that Discord is completely unusable in the Steam overlay, but that’s a separate issue entirely.
