I can't see metadata components in the Metadata GridIn order to be able to see the contents of the metadata grid selector, the Copado user has to:
a) Be granted all CRED permissions to the Push Topics object in the org where Copado is installed.
b) Has access to the Metadata API on the connected Org. This requires the Modify All Data permission. Please note that this is not in the org where Copado is installed but the org of the Org Credential where you are retrieving the metadata from.
You can achieve a) and b) either by editing the User's profile, or with a Permission Set.
