Using field groups in Kirby Field Toggle plugin or similar

Has anyone figured how to use field groups inside of the Kirby Field Toggle plugin?

I started a thread that covers what I am needing to do but it died off and I need get it figured out for my client.

Same blueprint, same template, different page content

This question has already been answered in the other thread you mention. Currently, field groups are not supported by the plugin, the feature request issue is still open.

Sadly, it’s not easy to identify field groups properly. I already tried some ideas and approaches but I couldn’t get it to work. I also looked for existing plugins that do something with field groups but couldn’t find one.

If anyone has an idea, please let me know.
