So this is in the context of a broader task. We are using datashader and we have a tile map and a Dynamic Map that controls the stream. There seems to be an issue when combining the three as I posted here [Tap Selection](https://discourse.holoviz.org/t/dynamic-map-with-tapselection/4426).

Doing what you suggested would give me an hv.Overlay.

What I am hoping to do is add to a plot using `hook` as a workaround? Is that possible? As stated above, it seems to work as they are added to the figure but they are not shown.
