Add Custom Plugin through onBeforeLoad

[estooksberry]

In standalone CKEditor4 I am able to add custom plugins to my React project through the onBeforeLoad. How can this be achieved with the Grapes JS CKEditor plugin? As this is not part of the CK Editor standard or full plugins, I cannot enable it through the config, and as this is React, I do not have an actual plugin directory to place the "file".

<CKEditor
    initData={}
    config={
        extraPlugins: 'myPlugin'
        toolbar:[{name: 'insert', items:['myPluginButton'] },
    }
    onInstanceReady={handleInstanceReady}
    onBeforeLoad={(CKEDITOR) => {
        myPlugin(CKEDITOR);
    }}
/>
