Add missing types

[ueman]

Description

This place was missing the types, so you could actually run into an issue where you pass incompatible types.

You could actually test this by enabling the strong language analyzer options:

analyzer:
  language:
    strict-raw-types: true
    strict-inference: true
    strict-casts: true

But I don't know whether that's something you want to do. I've briefly tried to enable them, and it shows a lot more issues. That's also why I didn't enable them as a test for these changes.

Breaking Change

Does your PR require plugin users to manually update their apps to accommodate your change?

While technically this is a breaking API change (you could pass an unrelated type), it's not a change in behavior (only passing correct types would make the code work)

We let the author merge after approval but it is not mentioned in the Contributing guideline. AFter the refactor, we will need to add more rules.

I don't have the rights to merge the PR, or maybe it's due to the failing "check for tests" job?
