[Adminjs & NestJS] how to get admin instance

[mohamad-zbib]

I am working on a project uses AdminJS 6.8 & NestJS 9.0 with @adminjs/nestjs 5.0.1.

I need to use adminJS.overrideLogin(....), I am searching for an object that can pass the instance of the used adminjs instance. how to get it?
I Used a cheap trick, but we should find a better way:

handler: async (req, res, context) => {
    const { resource, _admin } = context;
    _admin.overrideLogin({ component: Login });

    // ....
};

This is using an action handler, but i should login and run this event and logout to get the result.
suggest a better solution please.
