AX is structured information supplied by the app. A button may identify its role, title, and supported Press action.

00:00:18.000 --> 00:00:27.000
Each view has limits. Pixels do not directly encode a button action. AX can omit a custom control or provide incomplete information.

Use the evidence the app provides, then verify what changed. Accessibility access and Screen Recording are separate macOS permissions.
