Flame shield no recasting with key held?

Just switch from ps5 to pc.
On the controller I can hold flame shield button down & it’ll auto proc after cooldown.
No matter what key I bind it to, it will not activate unless I activate another skill.
( ice bolt, fire wall, even the basic skill )

Is there a way to make flame shield automatically come back on after cool down while holding the key it’s bonded to, with out having to active a separate skill?
