Adobe Acrobat Pro 2024 standalone (non-subscription) educator discounts?

I have been using Adobe Acrobat Pro 2017 standalone - however, I have just been notified that Apple will no longer support that app because they are phasing out Intel-based Rosetta on their silicon M chips. My 2021 laptop uses M1 chip, so at some point Adobe will cease to function. 

I purchased the 2017 app with teacher's discount. I see that there is such a thing as non-subscription Adobe Acrobat Pro 2024. But I can't figure out how to activate the teacher's discount. 

Thanks for your help.
