Decode base64 encrypted LogResult of "AWS Lambda invoke" in Windows PowerShell

I am not using Windows, but I head that Bash is available under Linux subsystem also. Inside of every lambda directory I have file invoke.sh with code like this:

NAME=getLineUpMapOUT=/tmp/awsLambdaOut.txtAWS_PROFILE=gms-ai \aws lambda invoke \--function-name $NAME \--payload '{"specs": ["RPM", "Energy"], "numberOfModels": 3}' --log-type Tail \$OUT |grep "LogResult" |awk --field-separator '"' '{print $4}' |base64 --decode |grep --color "$NAME\|$" --textcat $OUT | python3 -m json.tool

Example of output:
