Describe the bug:

As shown below, previously we had a create drilldown option available in the SLO embeddable but this option is not there any more.

8.14.1	8.15.1

This might be a regression that was introduced in #181930. In this ticket, we want to fix not having that option in the SLO embeddable menu.

Implementation hint

Provided by @Heenawter

If you take a look at the isCompatible method of the FlyoutCreateDrilldownAction, you should be able to determine which part of the API your embeddable is missing to make the "Create drilldown" action incompatible. if I had to guess, it is most likely either HasDynamicActions or HasSupportedTriggers that is missing (or possibly both) - you can take a look at how the Visualize embeddable supports drilldowns in src/plugins/visualizations/public/embeddable/visualize_embeddable.tsx, where they make use of the initializeReactEmbeddableDynamicActions function we provide through the EmbeddableEnhanced plugin start contract.

Acceptance criteria

• Bring back the create drilldown menu option for the SLO embeddable

I'm struggling with adding the dependency to embeddableEnhanced from the slo plugin

Fixed the previous error by changing the visibility of the embeddable-enhanced plugin to shared.
