    Sample for Screen Capture Allow List

    Note:

    • The name has to be mandatorily filled. At the same time, the publisher and signature aren’t mandatory. However, It’s recommended to add the relevantpublisher and signature to ensure that only the allow listed app can take the screenshots.
    • Without publisher and signature values, a malicious application with the same name can capture screenshots.
    • Also, you can add multiple apps to the Screen Capture Allow-list by adding multiple entries in this block.

    To get the publisher and signature information, see Get the publisher and signature information.

  6. Click Save draft and then click Publish Drafts.

  7. On the Publish Settings dialog box, click Yes.
