Scollable Text inside a Section

Hello I want to insert a scrollable area in the "roadmap" section. i want the section to stay there in its fixed height while users can scroll inside the section - is this possible? I am planning to insert more text and elements inside as well.

 managed to fix it 🙂 for anyone interested it is

section[data-section-id="BLOCKIDNUMBER"] {
  height: 800px;
  overflow:auto;
}

and use this free tool to find BLOCKIDNUMBER (this is section id number, not block id number) https://chrome.google.com/webstore/detail/squarespace-id-finder/igjamfnifnkmecjidfbdipieoaeghcff?hl=en
