1.15.2 Custom texture data & signature CitizensAPI

Hey would like to known if this is possible to set a custom skin with only texture data and signature without uuid ?

Because I've tried everything with the citizensAPI (latest):

Code (Java):

  Location l = player.getLocation();
            NPC npc = CitizensAPI.getNPCRegistry().createNPC(EntityType.PLAYER, "§4Banker");
   
            npc.data().set("nameplate-visible", true);

            npc.data().set(NPC.PLAYER_SKIN_TEXTURE_PROPERTIES_METADATA, Skin.HOSTESS.getTexture());
            npc.data().set(NPC.PLAYER_SKIN_TEXTURE_PROPERTIES_SIGN_METADATA, Skin.HOSTESS.getSignature());


            npc.data().set(NPC.PLAYER_SKIN_USE_LATEST, false);

            /*npc.data().setPersistent(NPC.PLAYER_SKIN_TEXTURE_PROPERTIES_METADATA, Skin.BANKER.getTexture());
            npc.data().setPersistent(NPC.PLAYER_SKIN_TEXTURE_PROPERTIES_SIGN_METADATA, Skin.BANKER.getSignature());
            npc.spawn(l);
            if (npc.isSpawned()) {

                SkinnableEntity skinnable = npc.getEntity() instanceof SkinnableEntity ? (SkinnableEntity) npc.getEntity() : null;
                if (skinnable != null) {
                    net.citizensnpcs.npc.skin.Skin.get(skinnable).applyAndRespawn(skinnable);

                }
            }*/

            npc.spawn(l);
            //npc.data().setPersistent(NPC.PLAYER_SKIN_UUID_METADATA, "sovve");
            //npc.data().setPersistent(NPC.PLAYER_SKIN_USE_LATEST, false);
           // npc.despawn(DespawnReason.PENDING_RESPAWN);
           // npc.spawn(l, SpawnReason.RESPAWN);

And the skin displayed is the skin named Banker not the custome texture one,
Any idea ?

EDIT: Sometimes it's working, sometimes not without changes, do not know why 0-o


Thanks !
