Hello, I'm looking for help to achieve invisibility effect, I have a fragment of the code but not work

@bgolus Hello, I got a video that does the effect I'm trying to do but does not give a tutorial on how to do it, I post the video and a screenshot to point out the effect I'm looking for, it's basically that the object that is behind is not visible of this "invisible" wall. I have a fragment of the code but not work

Link Video: https://www.youtube.com/watch?v=SNxFPUeSUfs

Code:

Shader "Invisible" { Properties { [PerRendererData] _MainTex ("Sprite Texture", 2D) = "white" {} _Color ("Tint", Color) = (1,1,1,1) [MaterialToggle] PixelSnap ("Pixel snap", Float) = 0 }

  SubShader
  {
      Tags
      { 
          "Queue"="Geometry+2" 
          "IgnoreProjector"="True" 
          "RenderType"="Opaque" 
          "PreviewType"="Cube"
          "CanUseSpriteAtlas"="True"
      }
      
      Cull Off
      Lighting Off
      ZWrite Off
 
      CGPROGRAM
      #pragma surface surf Lambert vertex:vert
      #pragma multi_compile DUMMY PIXELSNAP_ON
 
      sampler2D _MainTex;
      fixed4 _Color;
 
      struct Input
      {
          float2 uv_MainTex;
          fixed4 color;
      };
      
      void vert (inout appdata_full v, out Input o)
      {
          #if defined(PIXELSNAP_ON) && !defined(SHADER_API_FLASH)
          v.vertex = UnityPixelSnap (v.vertex);
          #endif
          v.normal = float3(0,0,-1);
          
          UNITY_INITIALIZE_OUTPUT(Input, o);
          o.color = v.color * _Color;
      }
 
      void surf (Input IN, inout SurfaceOutput o)
      {
          fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * IN.color;
          o.Albedo = c.rgb * c.a;
          o.Alpha = c.a;
      }
      ENDCG
  }

Fallback "Transparent/VertexLit" }

and this is the result that I have:
