### Bug description

When using the chalkboard feature and adding some annotations in a speaker view setting, the annotations are not mirrored to the main presentation.

This is an issue as usually one looks at the speaker view during a presentation on the laptop while the main audience looks at the mirrored slides behind/beside the speaker. For speakers, it's not easy to spot that things are not synchronized.

Adding annotations only on the main presentation view would require taking the mouse across screens which is fiddly and takes additional time.
