I have created a paid utility tool (here), which has a downloadable .exe file. I'd like a button that looks like the one on the screenshot below to my itch.io project page, since the only way users can currently donate is when buying for the first time, and I really don't see why someone would do that before they even tried the tool. Is it possible to somehow enable it? I tried setting different pricing and uploading other files, but couldn't get it to work (currently I removed the downloadable from the page, to be added soon).
So: Is it possible to add a 'Donate' button to my paid downloadable app's project page, bzw subpage `/donate`? Thanks! Any help/replies will be appreciated.
