AppSheet Workspace Integrations (such as inside Sheets and Drive) are expected to have screen reader support.
Accessibility functionality
Images should have descriptive text, the ability to use keyboard shortcuts similar to a standard website, and sufficiently descriptive text.
To move around, press Tab to select the different menu buttons and text and Enter to activate the button. In addition, you should be familiar with how to edit spreadsheets with a screen reader in order to prepare your sheet for use within AppSheet.
