Is there a way to filter devices based on tags or saved filters?

I have a small python code to connect to my Netbox using pynetbox.
Unfortunately, when I filter the devices with a certain tag, it just returns everything.

devices = nb.dcim.devices.all()
print(f"Total number of devices: {len(devices)}")
devices = nb.dcim.devices.filter(tags='custom_tag')
print(f"Number of devices with certain tag: {len(devices)}")
devices = nb.dcim.devices.filter(role='server')
print(f"Number of devices with certain role: {len(devices)}")

Output

Total number of devices: 10818
Number of devices with certain tag: 10818
Number of devices with certain role: 5994

But when using the same tag in web UI, I see 56 systems, only.
I also have saved the filter using the same tag, but don't know if there is a way to get only those using pynetbox.

I realized, despite Web UI showing tags, pynetbox accepts tag. That was my first mistake.
Secondly, I was using the tag name, instead of tag slug, It is working now.
