How your end-users make a donation
Once enabled for an event, logged in users with access to your event will see the chat with the donation model:
Clicking the donate icon will show a popup for your users to make a donation. A donation message that shows in chat is optional. Different amounts will change the color scale of the donation message making larger donations instantly recognizable even if you're not near your computer:
There are a few suggested amounts that will change based on your storefront's currency. Stores with currencies like Yen will see nice whole numbers like ¥1000 instead of direct conversions from USD.

Clicking Continue will bring your end-users to the final step where they verify payment details and complete the donation:
