• [X] I am not looking for support or already pursued the available support channels without success.

Version

v0.1.3

Expected Behavior

command.ExecuteContext(context.Background()) should create the context, and it should be retrievable with command.Context().

Actual Behavior

Currently the NewSyncCMD function runs init() and run() and after that the sync command is executed, therefore we cannot use command.ExecuteContext(context.Background()) to create a context, and then use it elsewhere with command.Context().
