Generally, you cannot use iframe with any ConfTool page because there are too many security issues (lsuch as click highjacking) and usability issues related to such an integration. For instance the height of each ConfTool page varies and the height of an iFrame is fixed, so people might have to scroll within the page and within the iFrame, which is very uncomfortable and not user-friendly.
There is one exception:
You can embed the ConfTool agenda via iframe.
Please go to:
Overview => Conference Agenda
In the menu bar, select "More" and then continue to select "View to Embed Page in iFrame" (see image).
Please use that view for your iframe.
The code could look like this:
<iframe
src="https://www.conftool.net/yourconference2024/index.php?page=browseSessions&print=embed&presentations=hide"
id="ctiframe" name="ctiframe"
width="930" height="2800"
scrolling="auto"
align="top"
frameborder="1" marginwidth="0" marginheight="0">
