I haven't personally tried any of them, but if they require specific integrations into RahiTuber then I'm afraid you're out of luck (for now).
So far, the best you can do within RahiTuber is to set up some animated throwable layers and States to trigger them, and have the animation restart each time it's triggered. There's an example of this here: https://www.twitch.tv/rahisaurus/clip/BoxySillyElephantFUNgineer-v64GflXI_DC5BMk-
If the throwing system lets you trigger a keypress or send a web request after something is thrown, then you can set that up to trigger a state within RahiTuber.
