For VFX and SFX spawning, the system uses the DA_EffectsDataTables data asset. Designed to keep all VFX and SFX references in the same place for easier change.

For each type: (Once, Trail or Loop) a data table must be defined

Here on identification name must be set for each effect. For VFX, you can also set parameters, removing the necessity of duplicating Niagara systems just to change the color, or the spawn amount, etc. This way is possible to reutilize the same Niagara system for multiple purposes by just changing parameters. (The parameters must be configured inside your Niagara system before).
