How to use ExtraFilters inside of "game.CleanUpMap"?

[LambadaCorez]

I need to keep some props and vehicles excluded from the map clean up.
Anyone have an idea on how ExtraFilters works? The code below that I tried didn't work.
Code Example:
local ExtraFilters = {}

ExtraFilters[1] = {ents.FindByClass("prop_vehicle_airboat")}
ExtraFilters[2] = {ents.FindByClass("prop_dynamic")}

game.CleanUpMap(false, ExtraFilters )

the wiki clearly states that it needs a list of entity classes, not a table of tables of entities.

[LambadaCorez]

Can you give me an example of a list of entity classes?

That's very bad.
game.CleanUpMap(false, {"prop_dynamic", "prop_vehicle_airboat"})
