Help creating access permissions on routes <Link state={ customItem: 'newItem'}

[efgomes]

I'm passing a new attribute to Link through state, which was the way I found to identify which module this route belongs to.

it's working

But I would like to know if this is the correct way to do this?

Another question, how can I resolve this typoscript error?

you can use it, but you could also use search params.
about that TS error, have a look at #1342 (comment)
