How to hook into the triggers mechanism from prosemirror-sync ?

Hello,
I would like to fire a trigger when there is db change caused by onSnapshot callback. AFAI to use triggers in need to wrap the base mutation but I don't find a way to pass the custom mutation to prosemirror-sync. Is there a way to achieve that except from patching the node_modules ?

No file or test is named. Start by tracing the onSnapshot callback and the base mutation path in prosemirror-sync, then determine how triggers are invoked for database changes and whether a custom mutation can be passed without patching node_modules. Done means the supported integration path, or the required project change, is clearly established.
