Where to put your own functions in laravel?

Question

Laravel

Guys, I recently took up Laravel, the question is this.
Let's imagine that some of the functions are provided by Laravel, some are pulled from the composer's libraries, but there are always a bunch of small functions that I implemented myself, but I don't want to drive them into a class, I also want to design them as a library, it's expensive to look for something similar, so the question arises - where Is there a place for such functions in the Laravel architecture? Is there any best practice for this?

Laravel has nothing to do with it.
composer solves this issue, or rather autoloading.

"autoload": {
    "files": [
        "app/helpers.php"
    ],
