How do I delete a Subtask

Hi, I’m new to this forum; forgive me if this has already been asked.

We are a small business and use asana frequently to create “Protocol” projects and “Email Templates” under specific Sections.

So, for example:
We have a section titled “Systems & Templates.”
Under this section, we have created Tasks Labeled as “Protocols” and “Email Templates,” where we create subtasks that have the details and additional subtasks with further details and just the order of how to complete certain protocols like reaching out to customers or changing something on our web platform.

The issue is some of these subtasks are no longer needed… how do I delete them?

tab+backspace quickly deletes any highlighted tasks or subtasks.
