About

This plugins adds only one command :Gitblame. This command shows git blame info about currently focused line

Lazy:

{
    "ring0-rootkit/gitblame.nvim",
    opts = {},
}

Also, you can add simple remap to use it:

vim.keymap.set("n", "<leader>b", ":Gitblame<CR>")

You can install it using other plugin managers, but I'm too lazy to add instructions for them (you'll figure it out)
