Increase the file upload size to 50mb in the app service

Using .Net core 8.0 and App service Deployment , need to increase the file upload size limit to 50 mb
implemented following things in the local and its working as expected but when it is deployed to app services its not working

Program.cs file 
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.ConfigureKestrel((context, options) =>
{
// Handle requests up to 50 MB
options.Limits.MaxRequestBodySize = 52428800;
})
.UseStartup<Startup>();
})
.UseSerilog()
;

startup file:
app.Use(async (context, next) =>
{
context.Features.Get<IHttpMaxRequestBodySizeFeature>().MaxRequestBodySize = 104857600; // unlimited I guess
await next.Invoke();
});

---

services.Configure<FormOptions>(o => // currently all set to max, configure it to your needs!
{
o.ValueLengthLimit = int.MaxValue;
o.MultipartBodyLengthLimit = 104857600;
o.MultipartBoundaryLengthLimit = int.MaxValue;
o.MultipartHeadersCountLimit = int.MaxValue;
o.MultipartHeadersLengthLimit = int.MaxValue;
o.ValueCountLimit = int.MaxValue;

});
services.Configure<IISServerOptions>(options =>
{
options.MaxRequestBodySize = 104857600; // Remove any limit
});

services.Configure<KestrelServerOptions>(options =>
{
options.Limits.MaxRequestBodySize = 104857600; // Remove limits for Kestrel
});

-----

in app settings file 
"Kestrel": {
"Limits": {
"MaxRequestBodySize": 52428800
}
},

---

In the project configuration we are not using web.config file , we need alternate solution , if we use the web.config settings 
<system.web>
<httpRuntime targetFramework="4.8" maxRequestLength="1048576" executionTimeout="120" />
</system.web>

<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="4294967295" />
</requestFiltering>
</security>

With this configuration it is working as expected in the app service but we are not web.config file as it is automatically generated
