There are 2 different ways to change the background:
1. Change the background color
Right click somewhere on the canvas, and then click “Add Background” to choose a color or an image as your background.
2. Choose an image as the background
Just like above, Right click somewhere on the canvas, choose “Add Background” and click the “Upload” button on the bottom, and then you can select the image you want in the cloud.
