Psionic Sorcerer: Psychic Strike with ongoing spells

https://media.wizards.com/2020/dnd/downloads/UA2020_PsionicOptions.pdf

Psychic Strike 6th-level Psionic Soul feature You have learned to channel additional psychic energy into your spells. Immediately after you deal damage to a creature with a sorcerer spell for which you expend a spell slot, you can roll your Psionic Talent die and also deal psychic damage to that creature equal to the number rolled. You can deal this extra damage only once per turn.

Does this work with an ongoing spell like witchbolt? Or something like Fire Shield?
