Using VSCode and Paket to add file to `.fsproj`

I'm using VSCode and Paket to add libraries from Nuget to an F# project/.fsproj file.

From VSCode, I use ctrl+shift+p and use the command Paket: Add Nuget Package (to current project) and enter

FsVerbalExpressions version 0.4.0

Unfortunately, Paket fails with the following error:

Paket version 3.23.2.0
Adding FsVerbaExpressions 0.4.0 to 
c:...\paket.dependencies into group Main
Resolving packages for group Main:
 - FsVerbaExpressions is pinned to 0.4.0
    Package not available.
      Message: Couldn't get package details for package FsVerbaExpressions 0.4.0 on https://www.nuget.org/api/v2.
Paket failed with:
    Could not find versions for package FsVerbaExpressions on https://www.nuget.org/api/v2.

I know that FsVerbalExpressions is available on Nuget. I need the older version because the project I'm working on is targeted at .NET 4.5 and the newer version of FsVerbalExpressions will only work with .NET 4.6.1.

Typos happen. Make sure you proofread your error messages before looking for answers that are already in front of you.
