Regarding the exclusive 'Magic Potion' & Link Issue

Resolved, thanks to @car 大大 🙏🙏🙏 Added event link images, please refer if needed: 1. The event page is on the homepage, please swipe left/right (Figs. 2, 3) to find it. 2. This is an in-app page, so there's no URL, refer to (Fig. 4). 3. According to the event description (Fig. 5), if there's no link, it doesn't meet the event requirements... 'What I don't give you, you can't have' (pure meme, not mocking 🙏), please report and protest to customer service about why it doesn't meet the requirements... 💢 ............ As the title says, I'm not too sure how to obtain it... After reading the text description, I still don't quite understand how to use it? Please advise, great masters 🙏 It's almost expired 😅
