Hi, Unless you have the complete source code, it cannot be modified, which is a safeguard for partners.
Also, if you are talking about AppSource Extension, only the publisher has permission.
PS: Business Central 2022 wave 2 (BC21) new features: Resource exposure policies for apps are on by default (“allowDebugging”: true, “allowDownloadingSource”: true, “includeSourceInSymbolFile”: true)
