  -- The setup below will automatically configure connections without the need for manual input each time.

  -- Example configuration using dictionary with keys:
  --    vim.g.dbs = {
  --      dev = "Replace with your database connection URL.",
  --      staging = "Replace with your database connection URL.",
  --    }
  -- or
  -- Example configuration using a list of dictionaries:
  --    vim.g.dbs = {
  --      { name = "dev", url = "Replace with your database connection URL." },
  --      { name = "staging", url = "Replace with your database connection URL." },
  --    }

  -- or
  -- Create a `.lazy.lua` file in your project and set your connections like this:
  -- ```lua
  --    vim.g.dbs = {...}
  --
  --    return {}
  -- ```

  -- Alternatively, you can also use other methods to inject your environment variables.

  -- Finally, please make sure to add `.lazy.lua` to your `.gitignore` file to protect your secrets.
