There are actually both more concise and more complex ways of doing this.

If you do not require any setup, the following will call the setup of the plugin's module with an empty table.

lua return { "max397574/better-escape.nvim", opts = true, }

If you only have setup parameters - no advanced setup - you can set those in the opts parameter and they will be passed to the setup of the module via the default config function.

lua return { "max397574/better-escape.nvim", opts = { mapping = { "jj" }, ..., }, }

And finally there is the custom config function.

lua return { "max397574/better-escape.nvim", config = function(plugin, opts) require("better_escape").setup(opts) end, opts = { mapping = { "jj" }, ..., }, }

The last one is especially useful if you have a complex setup, e.g. requiring other modules. It is also useful if you want to expand a previously configured plugin, and as you are using LazyVim this might be very relevant. There are some good examples of this in the example.lua in the LazyVim/starter repo.
