Is Starbucks testing boba?

Are there any rumors or reports that Starbucks, the popular coffee chain known for its diverse range of beverages, is currently experimenting with adding boba, a chewy tapioca pearl often found in bubble tea, to their menu? This would be a significant shift for the brand, as boba drinks have become increasingly popular among young adults and could potentially attract a new demographic of customers to Starbucks. Is the company looking to tap into this trend and offer something unique to its customers, or is this just a rumor without any basis in fact?
