How to dynamically change the route meta tag for sfc [https://github.com/hannoeru/vite-plugin-pages#sfc-custom-block-for-route-data]

[ghost]

the docs suggest using this block for custom meta data

`<route lang="yaml">
meta:
    layout: default
    title: My Offers
    action: is_view
    subject: inf_my_offers
    navActiveLink: inf-offer-my-offers
</route>
`

now how to edit this block and change its properties dynamically? if i want to change the navActiveLink property through javascript from inside the single file component, how do i do it?
