Has anyone tried the TikTok promote feature? And if so, what were the results like?

Hi everyone, I’m trying to boost my account to promote my twitch channel and I haven’t been getting nearly as many views as I used to. I wanted to know if the tiktok promote feature is actually beneficial for your account or it’s just a money grab by tiktok. Let me know your thoughts and feedback and if the feature is even worth it. Thanks!
