Executing stored procedures with a scheduled proces flow

I am still looking for a method to schedule stored procedures in a process flow and expected this in the 2021.2 release.

There doesn't seem to be any process action for this yet. But, could it be realized by using a 'dummy' HTTP connector (eg GET: www.nos.nl) or by using a Decision? 

… and then calling the desired stored procedure within the process procedure, like below:

create procedure prc_pf_send_notifications_pf_execute_stored_procedure
(
  @dummy text_100 output
)

as
begin

  -- Do not count affected rows for performance
  SET NOCOUNT ON;


    --control_proc_id:      process_pf_send_notifications
    --template_id:          process_pf_send_notifications
    --prog_object_item_id:  process_pf_send_notifications
    --template_description: 

    EXEC dbo.any_stored_procedure

end
go

Or is there a more elegant way?
