can not find alt text opction in web stories dashboard

Hello @rieiirir ! Thank you for opening your topic. There are two ways to add the alt text.

1. Upload an image in the media modal, navigate to the right side, then add a description in the Alt Text field.
2. In the Stories editor, on the left side media panel, hover over your image, then a dotted menu should appear on the top right corner. Click on the dotted menu > Edit meta data > enter a description in the text box.
