The system does not appear to have created a CP menu option to get to the store. Currently I am having to go through Developer, Add ons, Store to see the store dashboard. Is there a way I can create this button manually?
You could create a button... In EE3 to EE5, Setting -> Menu manager -> Manage your menuset -> Add menu item -> Single Link to your addon-link (you have to copy - paste from the address bar).
