name 'iface' is not defined

I run into this issue when filtering layers (from postgis) in QGIS4:

An error has occurred while executing Python code:

NameError: name 'iface' is not defined. Did you mean: 'self.iface'?
Traceback (most recent call last):
File "/Users/leon/Library/Application Support/QGIS/QGIS4/profiles/default/python/plugins/FilterLayersAtOnce-master/filter_multiple_layers_at_once.py", line 222, in filterOnlySelectedsAtOnce
layers = iface.layerTreeView().selectedLayers()
^^^^^
NameError: name 'iface' is not defined. Did you mean: 'self.iface'?

Thank you for your feedback. Yes, there was an issue with the “Filter selected layers” option. Can you please try again using the latest version (2.1)?
