How can I see a list of comments

A fellow developer has left comments in my code in a few commits. How can I go to one place in and see all the comments on my code?

Heya and welcome to the Gitlab community.

Go to your Group overview (on your left side of the screen) > Activity. When you click on Activity you will get a set of options like on the screenshot below. Click on Comments and you will see the list of comments.
