Open a second details page for the same record out of a details page for a conditional form with related hidden fields

Don’t know how to handle a specific use case where it’s needed to do this:

If you open a record in a details page there are many options in my app what to do with the record. So there are also more advanced handling needed than just to edit a record. So I wanted to use a conditional form.

But: I already have the details page opened. I can add a button which should open a details page again which I can also create but if I do like this, I can not use hidden fields with the details page records in the form, which is needed. Placing the form on the first item details page would work but is not the solution for this app.

I hope you can follow me. If not, I can record a video with explanation. But it is important to make this happen anyway.

Thanks for help!

What would help otherwise would be conditional logic on add or edit record forms.
