Cannot add property shouldBreakOutOnEnter, object is not extensible about payload

Hey @italodr in 3.0 the slate elements have to be wrapped slightly differently due to the structure of RSCs so your plugin needs to be inside a 'use client' component.

See this for an example of how a plugin is structured in our 3.0 slate package https://github.com/payloadcms/payload/blob/beta/packages/richtext-slate/src/field/elements/relationship/plugin.tsx

We have a few elements there so you can see how they've been restructured

Thanks a lot @paulpopus
