Merchant ID creation what goes in Description

I'm admin/ops for a small nonprofit just trying to set up Apple Pay for our donation page. We got to the register a merchant ID stage and it is asking me to enter a Description. It only says it can't contain special characters.

Who sees this Description? The donor/person paying? Is it just us? There's no guidance, and no examples.

It also would be helpful if there were more guidance for the Identifier field but at least that has an example.

Help! (Thanks!!)
