I wrote your request to work, and in the next version I will try to make such an example scene.
But right now I can only make a new video for you to show how it works:

Tooltips flicker when it has a component with Raycast Target - ON.
You have two ways to fix this:
1. Disable Raycast Target on all components in the tooltip prefab where it is enabled.
2. Online Maps / Troubleshooting / Not Interact Under GUI - OFF.

The "ModifyTooltipStyleExample" did the trick for me now.

Unfortunately, I couldn`t make work the UGUI example. It seems only to work on 2D markers and keep flickering when it shows on the canvas.
Nothing appears on the 3D markers.
Would be great to have a working scene example, when you have some spare time, as the UGUI is newer and easier to customize without code.

Thanks

Alternatively, I tried to use the "uGUICustomTooltipForAllMarkersExample.cs" but I didn't find a Tooltip prefab or container to see how it works and how to configure it. Do you have and example scene?

Thanks
