Figma jam files automatically change to the view mode

Help me please. When I created a figma jamfile then from a while it automatically has been changed to the view mode. And I don’t understand why and how to change it back to edit mode. It my own files, I created some time ago. I found a decision I add file to my drafts and so it became in edit mode and I delete the previous one. But I have to do that relatively often that is not convenient
