How to correctly handle InvalidScope in a file required by a class?

[kkmuffme]

class foo {
    protected function display_something() {
        echo "hello";
    }
    
    public function output_template() {
        require 'my-template.php';
    }
}

"my-template.php" uses $this->display_something() and I get InvalidScope error.
What is the best way to document that this file is loaded inside the "foo" class?

You should be able to use the undocumented /** @psalm-scope-this foo */

IIRC, it tells Psalm you're inside that class already
