Yes it should definitely work for the toggle - which is the 46204. The configuration parameters are identical to the decora 46203. It may work for several other newer dimmers too, including Honeywell which are almost the same. If you go to the Zwave alliance website and search for Jasco/Enbrighten/Honeywell and check the command class, if it lists “central scene”, this handler should work for any of those.
If anyone has alternative switches that work with this handler, feel free to share the information here and I can add them to the fingerprint. I would need the raw description from the device in the IDE to add the fingerprint, like this example:
mfr:0063 prod:4952 model:3135 ver:5.53
I also have a related handler for the on/off switch (NON dimmer) on this link- [OBSOLETE] GE/Jasco 46201 On/Off Switch
Here’s the info for the 46204 toggle from the Zwave alliance:
