Remove Atitlan branding on PowerPoint slides?

Is it possible to remove the Atitlan branding at the bottom of each slide? How would I do that?

I think they are footers in PowerPoint. To change a footer in PowerPoint, you can go to “View” tab, “Slide Master” option, change or delete all the footers from all slides, “Close” or go back to “Normal view”.

You will see all the footers in normal view will be changed or deleted.
