ssh agent popup does not appear

Hello,

I've been using 1p ssh agent on multiple platforms, but on windows in particular it's been giving me trouble. For whatever reason, in powershell, the ssh agent appears to be running, I can run a ssh-add -l and it gives me the keys I expect including my github key:

but if I run a git clone or git pull, the request fails with a permission denied error:

The 1 password prompt for key authorization never shows up and so no valid key is presented to the server. 

Any suggestions on how to debug this properly? This key is valid and I use it on osx and Linux without issue.
