Back Up Directory for Android (CalyxOS)

TL;DL What is the exact directory where the MySudo Security Keys are located so I may manually back them up?

In your documentation on your site it is stated that the security keys are stored on the device. I use CalyxOS and would like to manually back up said keys myself. I do back my phone with Seedvault but I can't find/don't know the folder name that the keys are stored in to be sure it is done. Thank you!
