Can you guys guide me how can I add Vim keybindings to the app?

[hp77-creator]

I really like vim and I was using Postman before. I had to use mouse a lot when switching collections or just even trying to enter some values into the input fields. It will be awesome to have vim keybindings in hoppscotch, I have read that it supports shortcuts and I have also seen that if I am using hoppscotch cloud, I can use a vimium type extension to add vim's functionality. But I want to integrate it for application as well. Looking for some pointers which can help me in this, I am newbie wrt to development. But I really want this.
