How to apply radial damage with destructible impulse as damage type?

hi,
I have this UGameplayStatics::ApplyRadialDamageWithFalloff function which works well for a rocket launcher on characters, when I tried adding a Detructible mesh and shoot it nothing happened to it(and I lowered the DM’s damage to 1), I guess that normal damage type doesn’t work for DM and then I saw that there’s a damage type named destructible impulse that might be the solution here.
My question is how do I create this damage type I couldn’t understand what am I supposed to do from the documantation
here is the code:

thanks ahead!
