Link CMS items to a form multi-select field

I’m adding a Webflow form that included a multi-item select field (can be select field, checkbox, etc. I have no preference) that pulls options from a recently updated CMS collection. Given that the collection is not static, I need to pull these options dynamically. Has anyone had experience building a form submission that pulls options from a CMS collection?

If you check the read only link, navigate to the CMS page, Athlete Template and go to Dashboard Section tab 3 (feel free to take a look at tab 2 to see the form for the new CMS items that I want to allow to populate the “Add exercises” field in page 3
