How to put checkmarks on a checklist in Google Docs

**Note:** This question is specifically about Google Docs on Android, not Google spreadsheet on Android. Instructions from this [page](https://www.controlaltachieve.com/2016/06/docs-checklists.html?m=1) shows how to insert a checklist using the Android app or Google Docs. I was able to follow those instructions on the Google Docs Android app, however, I need to then quickly and easily check off each item. The instructions on that webpage are given for a desktop web interface, because it refers to clicking the right mouse button and selecting an operation, but how do I do that within the Google Docs Android app? Is this impossible? I currently believe the answer is "no", but I hope someone will prove me wrong about that.
