No response or error message when pressing the Print button on a secure (medical) site

I am trying to print from a medical site. There is a “Print” button for printing a specific document. When I press that button in Brave there is no response or pop-up for the print dialogue.
The button works fine in Firefox, so I don’t think that it is the site that is broken.

I have tried enabling all cookies for the site. I have tried enabling re-direct for the site. What else should I try?

I don’t know how to reproduce the error without giving out the login and password - which I won’t.

I expected the print dialogue pop-up to appear so that I could select the printer, number of pages, and the Print button
