Hi,

I had an idea about building a button that would allow users to send money through the various payment gateways.

I do not know how to do it though, but it’s based on the Activity reactions plugin.
In practice, I would like to replace all the jpgs of the emoticons with the logos of payment gateways and modify the actions of the key which, instead of leaving the emoticon as a reaction, directs the user to the gateway URL to proceed with the transfer.

Would I do this first or create the plugin that must be compatible with the multisite and buddypress to show the keys on all subsites?
