How do you update packages on AWS Glue?

In the documentation I can see that we can add additional modules from pip using the following command %additional_python_modules nameOfModule

However, I would like to be using a later version of pandas and pyarrow than the ones currently installed, 1.0.4 and 0.16.0 respectively.

I have tried adding this at the top of the script in a notebook:

%additional_python_modules pandas==1.4.2, pyarrow==8.0.0

As well as passing these as parameters when doing a manual run, however, I still see the version numbers remaining as the standard out of the box versions, is this possible to do?
