Unable to install Input Shaping plugin

If I follow these directions (Upload and Start the InputShapingPlugin-master.zip in DWC), I get an error message that "Only a single file can be uploaded and started". I can drag the ZIP file in on the SYSTEM tab - it's gets unpacked and creates a folder for the plugin, but it does not show up on the Plugins tab.

I have turned up posts that say the documentation is incorrect, but I haven't found what works.

I have the Duet accelerometer. I have a few machines that are DWC 3.4.6, and a couple that are 3.4.5.

I can usually figure out the basics, but I've come up empty on this one.

You've downloaded this version?

https://github.com/Duet3D/InputShapingPlugin/releases/tag/v3.4.6

And your Duet and DWC are also on 3.4.6?

@Phaedrux No ... That was not the version of the plug I've been messing with. That one went in fine.

It's always the little things :-p. Thanks for the assist.
