Place it immediately after the donation alert in a stream highlight, then follow it with the Yaaaay cheer to celebrate the supporter before you return to the game. If another donation arrives soon after, repeat the same order so the thank-you stays the centre of each celebration.
About this sound
This is a short Russian voice clip, lasting about two seconds, in which a speaker says 'spasibo bolshoe za donat', thank you very much for the donation. It sounds warm and grateful, with the upbeat sincerity of someone thanking a supporter in the moment. The line feels personal and appreciative, making a small tip feel noticed and valued instead of passing by unmentioned.
