Update function from v1 to v2 if function install through the Plug-in

Update function from v1 to v2 if function install through the Plug-in

Hi,

I wan to update the one of the Function added under Developer Space > Functions as a deprecation warning is getting displayed for the same.

But I am seeing a message like "Sorry! You can not edit or delete this function as it has been installed through the Plug-in".

Please guide me how can I update this Function from V1 to V2.

Thanks.
