Normally, you can use the Capture UI by desktop app button to obtain screen captures from the Cloud browser, or on a local PC, but elements that are only visible when you mouseover them cannot be captured in this way.
When you want to capture elements this way, click the small downward-facing triangle button on the right of the Capture button, and enable the Capture after 5 seconds option.
When you click the Capture button in this state, there will be a 5-second grace period provided before the actual capture is taken, during which time you can display the necessary elements.
State in which the Capture after 5 seconds option is enabled (checked/in case of Cloud browser)
State in which the Capture after 5 seconds option is enabled (checked/in case of local PC)
Reload this option from the edit test case page, or click the Capture after 5 seconds option again to enable until the check is removed.
