How should you ask viewers for money? (the right way)

Not sure how honestly. Just starting out. Most of the people I see use streamlab or paypal direct donation. I feel like asking too early is a buzz kill. What would you recommend? Open for discussion.

Edit: It was really a simple question. I don't know why almost all comments are one sided. Most people say no,yet have all donation buttons lined up. It's just one is more direct, the other is indirect. If you really believe what you say, why not take away the donation option?
