Can I buy sp500 on Webull?

Excuse me, could you please clarify if it's possible to purchase the S&P 500 index on the Webull platform? I'm quite interested in diversifying my portfolio and the S&P 500 seems like a solid option, but I'm unsure if Webull supports such transactions. Additionally, could you perhaps provide any insights into the process of buying the S&P 500 through Webull, or if there are any specific requirements I need to meet before proceeding? I'd greatly appreciate your help in this matter.
