Can I implement features such as sending a friend's message?
In game sparks, using the "Message" function,
Send string to another user.
Subsequently, using the message handler on the client,
Send and receive messages to each other.
Can this function be implemented in Playfab?
I think it would be possible to use an action like a play fab rule.
I know there is a limit on indi tier, is it easy to get frequent api calls to limit?
