Intake-STAC: KeyError: 'open_stac_item_collection'

I downloaded the AWS Earth search notebook from the intake-stac examples and whithout changing anything. Just run the cells…

But I’ve got everytime the error: KeyError: 'open_stac_item_collection'

Here is my code:

%matplotlib inline
import intake
import satsearch

bbox = [35.48, -3.24, 35.58, -3.14] # (min lon, min lat, max lon, max lat)
dates = '2020-07-01/2020-08-15'

URL='https://earth-search.aws.element84.com/v0'
results = satsearch.Search.search(url=URL,
                                  collections=['sentinel-s2-l2a-cogs'], # note collection='sentinel-s2-l2a-cogs' doesn't work
                                  datetime=dates,
                                  bbox=bbox,    
                                  sort=['<datetime'])

items = results.items()

catalog = intake.open_stac_item_collection(items)

This is the result/error:

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)

     60     try:
---> 61         return gl[attr]
     62     except KeyError:

KeyError: 'open_stac_item_collection'

During handling of the above exception, another exception occurred:

AttributeError: open_stac_item_collection

After the solution of Kadir and replace intake_stac.catalog.StacItemCollection with intake.open_stac_item_collection, I’ve got the following error:
