[RPG] When you make an ability check to cast from a scroll, do you add proficiency bonus

dnd-5emagic-itemsproficiencyspellcasting

I am a 3rd level wizard and have a 5th level wizard spell on a scroll that I want to try and cast. I'm supposed to make an ability check (intelligence).

Is it a straight check?
Do I add my proficiency bonus?
Can I make an arcana skill check instead?

It is just a straight check

Spell Scroll (DMG 200)

If the spell is on your class's spell list but of a higher level than you can normally cast, you must make an ability check using your spellcasting ability to determine whether you cast it successfully. The DC equals 10 + the spell's level. On a failed check, the spell disappears from the scroll with no other effect.

Ability Checks (PHB 174)

To make an ability check, roll a d20 and add the relevant ability modifier. As with other d20 rolls, apply bonuses and penalties, and compare the total to the DC.

No bonuses or penalties are described in the Spell Scroll description, so you just add the modifier and nothing else.
