Once your presentation is open in the editor, click Edit Text at the bottom of the screen.
A panel will open on the right side listing every text element on the current slide.
Click into any text field and make your changes directly.
When you're done, click Apply Changes to save.
Repeat for each slide you want to update.
That's all!
