enableGridContainer() - modify .container class

Does anyone know if it is possible to modify the default class returned for the container div when using $enableGridContainer()?

Currently it returns <div class="container"> whereas I would like to have <div class="container-xl">

I believe this comes down to implementing your own grid framework, but that could then just extend the existing Bootstrap one if you wanted. Then there’s a function that controlls the container div:

    public function getPageThemeGridFrameworkContainerStartHTML()
        return '<div class="container-xl">';

Thank you @mesuva , I’ll give that a go.
