Create Glowing Shader in Unity Shader

Hi everyone, I wanted to create this kind of shader



I created this using shader graph in LWRP and my project is using standard pipeline and i cannot upgrade because it's a pretty huge project with lot many complexions.

So I wanted to do the same effect using shader editor or amplify. I don't know much about amplify, it would be grateful if anyone can help me in converting my shader to amplify or help me with shader editor. I have created a transparent shader using shader editor, and here is the effect of how it is looking.



and here is the code for shader editor,

Code (CSharp):

1. Shader "Custom/LightIntensityShader"
2. {
3.     Properties
4.     {
5.         _Color ("Color", Color) = (1,1,1,1)
6.         _MainTex ("Texture", 2D) = "white" {}
7.         _Transparency ("Transparency", Range(0.0,0.5)) = 0.25
8.     }
9.     SubShader
10.     {
11.         Tags { "RenderType"="Transparent" "Queue"="Transparent" }
12.         LOD 100
13.  
14.         ZWrite Off
15.  
16.         Blend SrcAlpha OneMinusSrcAlpha
17.  
18.         Pass
19.         {
20.             CGPROGRAM
21.             #pragma vertex vert
22.             #pragma fragment frag
23.             // make fog work
24.             #pragma multi_compile_fog
25.  
26.             #include "UnityCG.cginc"
27.  
28.             struct appdata
29.             {
30.                 float4 vertex : POSITION;
31.                 float2 uv : TEXCOORD0;
32.             };
33.  
34.             struct v2f
35.             {
36.                 float2 uv : TEXCOORD0;
37.                 UNITY_FOG_COORDS(1)
38.                 float4 vertex : SV_POSITION;
39.             };
40.  
41.             sampler2D _MainTex;
42.             float4 _MainTex_ST;
43.             float _Transparency;
44.             float4 _Color;
45.  
46.             v2f vert (appdata v)
47.             {
48.                 v2f o;
49.                 o.vertex = UnityObjectToClipPos(v.vertex);
50.                 o.uv = TRANSFORM_TEX(v.uv, _MainTex);
51.                 UNITY_TRANSFER_FOG(o,o.vertex);
52.                 return o;
53.             }
54.  
55.             fixed4 frag (v2f i) : SV_Target
56.             {
57.                 // sample the texture
58.                 fixed4 col = tex2D(_MainTex, i.uv) + _Color;
59.                 col.a = _Transparency;
60.                 // apply fog
61.                 UNITY_APPLY_FOG(i.fogCoord, col);
62.                 return col;
63.             }
64.             ENDCG
65.         }
66.     }
67. }
68.  

I just add transparency factor in shader editor and I don't know how to make the border glow and center transparent. Please guide me on how can i proceed.
