Accessing Particle emitter

Hello. I am trying to do a simple shape and color change on the emitter in a particle.

I manged to do it using the UnityEditor namespace but I won't be able to use the script once it builds.

How can I change the shape and color of the emitter in code? or Is it possible to use the unityeditor namespace in a build?

Here's the code I used:

 ParticleSystem particleSystem = GetComponent<ParticleSystem>();
 particleSystem.startColor = new Color(particleSystem.startColor.r, particleSystem.startColor.g, particleSystem.startColor.b,1);
     
 SerializedObject psSerial = new SerializedObject(particleSystem);
     
 psSerial.FindProperty("ShapeModule.type").intValue = 0;
                     psSerial.FindProperty("ColorModule.gradient").FindPropertyRelative("maxGradient").FindPropertyRelative("key0").colorValue = new Color(Color.yellow.r, Color.yellow.g, Color.yellow.b, 1);
                     psSerial.FindProperty("ColorModule.gradient").FindPropertyRelative("maxGradient").FindPropertyRelative("key1").colorValue = new Color(Color.yellow.r, Color.yellow.g, Color.yellow.b, 1);
                     psSerial.FindProperty("ColorModule.gradient").FindPropertyRelative("maxGradient").FindPropertyRelative("key2").colorValue = new Color(Color.yellow.r, Color.yellow.g, Color.yellow.b, 1);
 
 
 //...
     
 psSerial.ApplyModifiedProperties();
