Where to edit/update Terms template created in Terms Library?

Content (required):

Hi - we've created Terms template on Terms Library and it was successfully approved and being used on some sourcing event. Now we want to update/create some revision of this Terms template, but we can't find where should we update it.

On the Terms Library all we can see is Create Template and no Manage Terms Template to see existing template?

Can you please advise where we can find and update the created Terms template? I'm not sure if we are just missing some role/access or config.
