Answer 1

You can pass arguments to the command object like so;

    command: {
        id: 'editor.action.triggerSuggest',
        title: 'operator_additional_suggestions',
        arguments:['apple']
      },

and access it in the registered command;

    editor.registerCommand('editor.action.triggerSuggest',(_:any,...args:any[])=>{
       // access the arguments here
     })
