after installation with zplug, zaw does nothing in response to ^x

[brandondrew]

I've just installed zaw with zplug

zplug zsh-users/zaw

and disabled all other zplug plugins, and confirmed that zaw is in fact installed:

brandon@Brandons-MacBook-Air ~ % zplug status
[zplug] Start to get remote status 1 plugins in parallel

 ✔  Up-to-date            zsh-users/zaw

[zplug] Elapsed time: 0.7313 sec.
 ==> All packages are up-to-date!

but when I enter ^x I see no response. According to the README I should see a list of sources at this point.

My Zsh version is 5.8:

brandon@Brandons-MacBook-Air ~ % zsh --version
zsh --version
zsh 5.8 (x86_64-apple-darwin20.0)

zaw-print-src seems to verify that zaw is installed:

brandon@Brandons-MacBook-Air ~ % zaw-print-src

Hitting ⌥ x and typing zaw successfully shows a list of sources.
