Item.create

void create(secret.collection.Collection collection,  secret.schema.Schema schema,  string[string]  attributes,  string label,  secret.value.Value value,  secret.types.ItemCreateFlags flags,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

Create a new item in the secret service.

If the flags contains secret.types.ItemCreateFlags.Replace, then the secret service will search for an item matching the attributes, and update that item instead of creating a new one.

This method may block indefinitely and should not be used in user interface threads. The secret service may prompt the user. secret.service.Service.prompt will be used to handle any prompts that are required.

`label`	label for the new item
`value`	secret value for the new item
