I am struggling to understand why my new 13” M4 IPad Pro will not connect to my LG Ultrafine 5K Monitor using the OEM thunderbolt 3 connection cable, am I right in thinking the M4 iPad Pro does NOT support Thunderbolt 3 and ill need a USB-C connection dongle? If so any recommendations? my M3 MacBook Pro connects without issue. I have tried to Google this but I fell into a rabbit hole.

The iPad Pro M4 USB-C/USB4 port does indeed support Thunderbolt 3:
iPad Pro 13‑inch (M4) - Tech Specs - Apple Support
Assuming that you are in fact using a Thunderbolt 3 cable (ideally of Apple origin), if you are encountering difficulties, you would be best advised to seek assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page.
Alternatively, you can initiate and manage your support cases from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

Although perhaps more difficult due to the bulk of the monitor, you might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to offer assistance:
