Acces the actual entry in a matrix field _partial

[FrDH]

How can I acces the actual entry (the "page") inside a _partial template?
For example, the template "_partials/entry/faq" is automatically included when the "faq" (matrixfield) entry type is used in a ck-editor field. In the template, the entry variable points to the matrixblock, entry.owner points to the ck-editor and entry.owner.owner points to the "page".
Since the nesting level can be infinite, is there a good way to access the page? I currently have this in my "_partials/entry/faq" template :

    {% set owner =
        entry.owner.owner.owner.owner.owner.owner ???
        entry.owner.owner.owner.owner.owner ???
        entry.owner.owner.owner.owner ???
        entry.owner.owner.owner ???
        entry.owner.owner ???
        entry.owner
    %}

Not my proudest piece of Twig...

You're looking for getRootOwner(), which was added in Craft 5.4:

{% set owner = entry.getRootOwner() %}

Thank you @mmikkel (I was on 5.3 but after updating all worked well)
