Thank you!
Yeah, we have a special section for apps in consideration, and I guess your assistant found this page. I am sorry for any confusion caused!
As for your use case, you just need a floating button, that triggers a donation popup form, am I right?
Yes
This would be great for my Boy Scout troops google site!
@Max What is the status of the donation button research? I have now launched a second site. Stephanie
