Combine PDF Files on Mac Sonoma OS

The online Mac User Guide provides instructions for combining multiple files into a single PDF file (Combine files into a PDF on Mac - Apple Support). I looked at the instructions for Monterey, Ventura, Sonoma, and Sequoia -- they are all the same.

Like Bob Bradley in May 2023 running Monterey (Combine files into PDF - Apple Community), I followed those instructions on my Mac running Sonoma, and they don't work.

SETUP: The PDF files to be combined are all in one folder; there are no other files in that folder.

ATTEMPTS:

A. I highlight my 3 files, click on Create PDF in the Preview panel, and nothing happens.

OR

B. I highlight my 3 files, right-click on the highlighted files to bring up a menu, roll down to Quick Actions, select Create PDF, and nothing happens.

OR

C. (Based on a suggestion from the User Community) I highlight my 3 files, Click on Finder's 'File' menu, roll down to Print and click it, and there is no Print dialog from which to select 'Save as PDF' -- as is true of any time you try to print from Finder (rather than printing from an opened file). So the files do print, but that doesn't help me create a PDF document that has my 3 original files combined end-to-end.

Sadly, Mr Bradley was left swinging in the wind in 2023. Let's get a working answer now, in 2024. On Mac OS running Sonoma (me) or Monterey (Mr Bradley), how can one combine files end-to-end (i.e. concatenate) to form another file, one of type PDF ?
