Hi @N_Saito
Clicking on specific coordinates is not possible in the extension. Please see this discussion for details:
Regarding your other concern:
Are those buttons inside an iframe, or are they within the main parent frame? One way to check this is to do the following:
- Right-click inside the button
- Select the "Inspect" option - which is usually the last option in the menu.
- A panel will open on the right side.
- Switch to the Console panel from the top.
- Check the value of the dropdown right below it. Does it say "top" or does it mention a frame's name?
