I'dont know z axis

Hello, I want the player to go to the waypoint blip position, but when I want to set entity coordinate, I don’t know what to put for z

My code :point_down:

RegisterCommand("tpw", async (source) => {
    const blip = GetFirstBlipInfoId(8);
    const coord = GetBlipCoords(blip);
    const blipX = coord.x;
    const blipY = coord.y;
    const blipZ = ?;
    SetEntityCoords(GetPlayerPed(-1), blipX, blipY, blipZ, true, false, false, false);
})
