Modding Help I'm trying to change the projectile type of the guided rocket ability.

Right now I'm making a Jötunn mod (it's a guided fusion rifle from destiny 2) and I'm pretty much done except for one thing :

I'm trying to change the look of the guided rocket ability ("altAbilityType" : "guidedrocket",) to use the "fireplasmarocketstatus" (it's a vanilla projectile btw).

I tried adding the line ("projectileType" : "fireplasmarocketstatus",) under the "altAbilityType" but it did nothing.

Any idea ?
