Strapi v4 beta is live 🥳

Hi, thanks for the release. I just installed a v4 instance and I can see the plugins section in admin panel is still under construction.
How do I install and enable e.g. the graphql plugin?
And also I can see that the latest version of strapi-plugin-graphql is still 3.6.8, this one is supposed to work with strapi v4 for now?
