How to set a theme on a picker AND some other options.

[JustLinuxUser]

I can do this:

		builtin.live_grep({
			additional_args = function()
				return "--follow"
			end,
		})

Or this:

		local ivy = require("telescope.themes").get_ivy()
		builtin.live_grep(ivy)

But not both?
I know I can set defaults while doing telescope.setup(), but can I set both a theme and some other args, when calling a picker from lua?
