Why does twitch use Pepe?

Could you please elaborate on why Twitch employs the use of Pepe? It seems intriguing to me how this popular meme has become a fixture within the streaming platform's culture. Pepe, originally just a harmless cartoon frog, has certainly evolved over time, taking on various meanings and interpretations. Is it a way for Twitch streamers to connect with their audience in a more casual, relatable manner? Or does it serve a deeper purpose, perhaps as a form of inside joke or cultural reference? I'm genuinely curious to understand the motivation behind this choice, and how it fits into the overall ecosystem of Twitch.
