init restore from deep glacier on all files in aws s3 bucket using aws cli

I have an AWS s3 bucket with a lifecycle attached to it. The lifecycle has moved all the files into Deep glacier.

Now I want to restore all of them. Unfortunately in the GUI (s3 console) I cannot select the entire bucket or parent folder and simple click "init restore". I can only select files individually which is very tedious.

Therefore I thought about using aws cli.

I figured out the command to list all Deep Archive files already:

aws s3api list-objects-v2 --bucket my-backup-bucket --query "Contents[?StorageClass=='DEEP_ARCHIVE']" --output text

However, I would need a command to init restore on all the files listed by the command above. Any idea how to do that?

(there are many related questions, but I didn't find one matching my exact setup using aws cli)

Update
Meanwhile I found the commands to iterate over all files:

# use awk to select filepath ("key") from output:
aws s3api list-objects-v2 \
  --bucket my-backup-bucket \
  --query "Contents[?StorageClass=='DEEP_ARCHIVE']" \
  --output text | awk '{print substr($0, index($0, $2))}' | awk '{NF-=3};3'  > backup_filelist.txt

# run init restore command on every file individually:
while read filename; do 

  aws s3api restore-object \
     --bucket my-backup-nas 
     --key $filename \
     --restore-request '{"Days":25,"GlacierJobParameters":{"Tier":"Standard"}}' ; 

done < backup_filelist.txt

I'll update this answer, in case everything is working correctly...

** UPDATE **
Everything working correctly -> case closed!
