Here, `:ensure t` should be used, as explained below:

The line `:demand t` is an option that can be passed to the
"use-package" macro to ensure that the package is loaded immediately,
rather than being loaded lazily. This is useful when you want to make
sure a package is loaded before using any of its features.

The line `:ensure t` is another option that tells "use-package" to
install the package if it is not already installed. This is useful
when you want to automatically download and install packages from a
package repository like MELPA or ELPA.

This change is also necessary. Thank you for pointing this out.
