Mask feature in OneNote

Hello, I'm using OneNote to take my notes. I'm looking for a mask feature where I can put a mask on some information of my notes, and will be able to reveal the information by tapping on it, and help me revise my notes. Is there any feature like this in OneNote?

    Thank you for your reply, actually I have checked the collapsible section feature in https://onenote.cloud.microsoft/, but it is not what I’m looking for. It is only beneficial to hide the entire paragraph or line, but I’m unable to hide some specific information within a line. I have read a https://notabilityforpc.co/onenote-vs-notability/ of OneNote with another note taking app which contains a tape feature, and we can draw it where we want and reveal the information after tapping on it. Is this type of feature available in OneNote? 

  • You may consider collapsible outlines to hide and reveal information:

    1. Create a hierarchy of text:
      • Type your main prompt or question.
      • Press Tab to indent the answer or explanation below it.
    2. Collapse the content:
      • Hover over the top-level text.
      • A small handle or + icon will appear.
      • Click it to collapse the indented content underneath.
    3. Reveal on demand:
      • Tap or click the + icon to expand and view the hidden content.
