There is likely a reason why your friend has joins off, Roblox should always respect privacy settings no-matter the scenario. In-fact Roblox is still falling-behind in respecting these settings requiring people (like me) who are testing experiences under an NDA to be selective with who we friend.
Personally I feel that this should be up to the game developer.
VoiceChat API would satisfy this enough so games can handle all this themselves.
ScreenshotHUD API will be announced in a seperate announcement, they probably should have announced that first so people don’t get confused.
Yeah, would be nice to see more functionality being exposed to developers, currently developers are locked to specific UI that does not fit the style of most games and is inconsistent because functions that communicate with CoreScripts tend to not be maintained (for example, the PromptFriendRequest CoreGui via SetCore hasn’t been updated since 2017 and looks horrible)
