 [@Petro31] adjust the behavior for template entities using the `relative_time`

-**New `is_hidden_entity` function**
+### New `is_hidden_entity` function <!-- omit in toc -->
 
 The brand new `is_hidden_entity` function was added by [@depoll], which can tell
 if a given entity has been marked "hidden" or not. This function also works
 as a test. Cool!
 
-This example returns a list of all entities in the kitchen area,
-that are not hidden.

-**New `areas` function**
