How can I extend the organization plugin schema ?

I want to extend the schema of the organization plugin to include custom fields. By default, it includes name, slug,logo and metada but I need to support additional fields for each organization, like:

description
schedule
socials
etc

I tried to extend the schema directly, but it doesn't seem to work. Is it possible to extend the built-in plugin schema?

If not, would creating a custom plugin inspired by organization be the right path?
