TailwindCSS Support?

Is there a way to try the Tailwind addon with an already licensed copy of Pinegrow?
Following these instructions:

It suggests this:

If you already have Pinegrow Web Editor, but don’t have the Tailwind Visual Editor add-on you can start a trial in Support → Purchase & Activate under Add-ons Tailwind Visual Editor.

However, this starts a full trial. Since I already have a licensed copy of Pinegrow, can I trial the Tailwind Addon with it?

Thanks.
