Find views and sheets that show a specific element

[Mo_Ody]

try this.

The script narrows the selection to only the category of the selected element.
Searches in BuiltInCategory.OST_Views and BuiltInCategory.OST_Sheets view category

If you don’t need both, just remove one and the script will run even faster.
