Unable to read appsettings.json keys which have dots

I am trying to access appsettings.json properties into NLog.Config file. I am writing rules in nlog and accessing loglevels from appsettings using configsetting layout renderer. It is working fine with normal properties (Microsoft), using below code

<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel.Microsoft}" writeTo="logfile,Loggly" />

With properties that have dot in name (Microsoft.Hosting.Lifetime) I am not able to read the value

<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel.Microsoft.Hosting.Lifetime}" writeTo="logfile,Loggly" />

Json sample below:

 "Logging": {
    "LogLevel": {
      "Default": "Error",
      "Microsoft": "Information",
      "Microsoft.Hosting.Lifetime": "Error"
    }

I tried below but nothing worked so far

<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel'.Microsoft.Hosting.Lifetime'}" writeTo="logfile,Loggly" />
<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel.'Microsoft.Hosting.Lifetime'}" writeTo="logfile,Loggly" />
<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel.Microsoft\.Hosting\.Lifetime}" writeTo="logfile,Loggly" />
<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel.Microsoft/.Hosting/.Lifetime}" writeTo="logfile,Loggly" />
<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel'.[Microsoft.Hosting.Lifetime]'}" writeTo="logfile,Loggly" />

EDIT 1: Tried Rolf Kristensen's solution and it is partly working with one minor issue. Logs are working as per loglevel set with just one minor issue.

My nlog.config file settings

<logger name="Microsoft.Hosting.Lifetime*" minlevel="${configsetting:item=Logging.LogLevel.Microsoft\\.Hosting\\.Lifetime}" writeTo="logfile,Loggly" />
<logger name="Microsoft.Hosting.Lifetime*" maxlevel="${configsetting:item=Logging.LogLevel.Microsoft\\.Hosting\\.Lifetime}" writeTo="void" final="true" />
<logger name="Microsoft*" minlevel="${configsetting:item=Logging.LogLevel.Microsoft}" writeTo="logfile,Loggly" />       
<logger name="Microsoft*" maxlevel="${configsetting:item=Logging.LogLevel.Microsoft}" writeTo="void" final="true"/>
<logger name="*" minlevel="${configsetting:item=Logging.LogLevel.Default}" writeTo="logfile,Loggly" />

appsettings.json set

 "Logging": {
        "LogLevel": {
          "Default": "Information",
          "Microsoft": "Error",
          "Microsoft.Hosting.Lifetime": "Information"
        }

Expectation is that for Microsoft.Hosting.Lifetime rule it should push logs till and including Information level to void. But its pushing till Error level to void. I think it is picking the loglevel set for Microsoft.

Logs taken from nlog internal logs:

2022-08-25 13:09:30.7512 Warn Logger: Microsoft.Hosting.Lifetime configured with duplicate output to target: FileTarget(Name=logfile). LoggingRule with NamePattern='Microsoft*' and Level=Error has been skipped.

NLog.Extensions.Logging v5.0.2 have been released. Where you can do this:

${configsetting:item=Logging.LogLevel.Microsoft\\.Hosting\\.Lifetime}

Or you can do this:

${configsetting:item=Logging.LogLevel.Microsoft..Hosting..Lifetime}
