Updating/Adding Sharepoint Hyperlink Field to a new list item

Hi all,

I have two SharePoint lists List A is a list of Qualifications and List B is a list of Scheduled Courses.

In List A the is a hyperlink field to an Icon/picture, this picture is displayed in Gallery in PowerApps.

In List B trainers/staff enter when they are holding courses and the details.

I need to know how I can get Power Automate when an item is created/modified in List B to update that item with the Hyperlink from List A so that PowerApps can show the correct icon/image for each item relative to the course that was selected.

Hope that makes sense

Thanks in advance
