We can add text to the editor using above icon. Once it is added, a sidebar will open on the right side where we can set text and also we can change the visual settings like Text Format (refer below image).
Here also we can perform operations like
delete, drag, resize, rotate and can use
On Board Alignment options in the same way as we do in images.
Once our changes are done, we can save it via
Apply Changes button on the bottom of the sidebar.
