It says:

> Opening chat in Feishu > Make sure you've installed the latest version of Feishu if the content doesn't open. > Already installed Feishu? <Open Now>

From what I can tell it's a "productivity" app? Looks like some microsoft teams kinda thing. I don't think that's z.ai's parent company, or am I missing something?
