How to add vyper-lsp as a completion source for blink when using lspconfig?

[dezly-macauley]

To be clear on what I'm trying to do

This is my minimal blink_cmp.lua config:

return {

    {
	"saghen/blink.cmp",
	enabled = true,
	dependencies = {
	    "rafamadriz/friendly-snippets"
	},
	build = "cargo +nightly build --release",
	config = function()
	    require("blink.cmp").setup({
		signature = { enabled = true },
	    })
	end
    }

}

This how I set set up lspconfig to work with blink:

return {

    {
	    "neovim/nvim-lspconfig",
	    enabled = true,
	    config = function()
	    -------------------------------------------------------------------
		local lsp = require("lspconfig")
		local blink_cmp = require("blink.cmp").get_lsp_capabilities()
	    -------------------------------------------------------------------
		-- Rust
		lsp.rust_analyzer.setup({
		    capabilities = blink_cmp
		})

		-- Lua
		lsp.lua_ls.setup({
		    capabilities = blink_cmp
		})

	    -------------------------------------------------------------------
	    end
    }

}

vyper-lsp is not available on this list: https://github.com/neovim/nvim-lspconfig/blob/master/doc/configs.md
Nor is it available as a community source.

This is the recommendation from vyper-lsp:
