How to do a CWT with the mexican hat wavelet?

The documentation for cwt (2018b) says that only 3 wavelets are supported: morse, bump and amor.
However, the waveletAnalyzer GUI tool (selecting the Continuous Wavelet 1-D) allows many more options, such as haar, mexh, gaus, etc. In fact, the morse/bump/amor options aren't even available in the GUI tool. So how can I perform a CWT on a signal with a mexican hat wavelet without using the GUI tool? Is there another function aside from 'cwt' which does this?

Did you ever resolve this issue? I am having the same problem.
