Deleting Branches

👋 Hey team, how would I go about deleting branches that are all the parent of my primary branch? When I try to delete it, it doesn't work since Neon says the parent branches have children, but I can't delete the main (primary) branch because when that's where the most recent data is. When I try to copy that data into another branch, the main (primary) branch becomes the parent of the new branch, meaning I can't delete the original main branch either. E.g. in the attached screenshot, I want to be able to delete all the parent branches. This will help free up some storage. Please let me know if I can provide any additional information. Thank you!
