Convective cooling in COMSOL 5.2

Hi,
I am trying to learn COMSOL modelling by designing a simple block to study joule heating. There are certain videos available describing the joule heating in a fuse on a circuit board, I have been following this one in particular (www.youtube.com/watch?v=p0eXEPP9Aao&nohtml5=False) but my COMSOL interface looks different than this one and it doesn't allow me to access 'Convective cooling' through the Joule heating module. I have tried searching in the search bar but only convection-diffusion shows up which I don't think I need.
Any suggestions on how to add convective cooling to my model?
Please let me know if more details of the model are required.

Thanks in advance.
