Log a list of files and open them with vscode CLI (creating a Shell macro)

I'm trying to create a macro on my shell.

The operation I'm trying to automate is this one:

Find all the files containing TEXT_TO_SEARCH, and open them with VSCODE

I can do this with a one-liner

$ code $(git grep TEXT_TO_SEARCH | cut -d: -f1 | sort -u)

so my first step was adding the following function to ~/.zshrc

cgrep() {
  code $(git grep "$1" | cut -d: -f1 | sort -u)
}

and then

$ cgrep TEXT_TO_SEARCH

This works.

Now I'm trying to add an extra feature:

Before opening each file with VSCode, echo to the console "Opening FILE_NAME"

First I've tried this

cgrep() {
  grep_results=$(git grep "$1" | cut -d: -f1 | sort -u)
  for file in $grep_results; do
    echo "Opening $file"
    code $file
  done
}

Note that grep_results is a "vertical list" i.e.

$ echo $grep_results

src/path1/FILE1.py
src/path2/FILE2.py
src/path3/FILE3.py

This way the for loop considers the first file as the whole grep_results and it opens FILE3.py (not src/path3/FILE3.py).

I've also tryied this (with the help of GPT)

cgrep() {
  grep_results=$(git grep "$1" | cut -d: -f1 | sort -u)
  echo "$grep_results" | while read -r file; do
    echo "Opening $file"
    code "$file"
  done
}

This way I can open just the first grepped file, and I get a message I don't want from VSCode and I don't actually understand

$ cgrep TEXT_TO_SEARCH

Opening src/path1/FILE1.py
Run with 'code -' to read from stdin (e.g. 'ps aux | grep code | code -').

Solved, with the help of @Gilles 'SO- stop being evil' in Unix&Linux StackExchange (his full answer here).

This is my final version

cgrep() {
    grep_results=($(git grep -l $1))
    for file in "${grep_results[@]}"; do
        echo "Opening $file"
        code $file
    done
}
