Edit existing product tag (correct a typo for example)

[MCOFA]

Is it possible to modify an existing product tag? For example, is it possible to change "apple" to "apples"? Please explain where.

By the way - I'm using "Studio" theme, a Shopify gen 2 theme.

Still hoping to find a solution to edit an existing tag. It's probably something simple - or just not possible. The alternative would be to delete the existing tag and create a new one, and then reassign it to all the products...
