2023 TCR Advanced Disc 1 integrated handlebar comparability?

Hi all, I was recently told by a bike fitter to get a new set of handlebars (38cm) and I was looking around the market and a set of Integrated handlebars seem really appealing but I’m not too sure about the little details about what needs to be compatible on my current set of stock handlebars to make the switch. If anyone can provide any information about this it would be much appreciated.

Also if anyone has recommendations for handlebars (especially on AliExpress as I am on a budget) they would also be very useful)
