Answer 1

Better save that code in your profile and attach the link on the original question. The limits on characters had cropped your text, and you end up having to write more on the "Answers" section, which risk to confuse others thinking you have had an answer and refrain from answering.

In case you didn't know how;
● Go to your profile → Codes section
Create new code, and save it.
● In code editor, copy URL from address bar if you're on web browser. If you're on mobile app tap on Share button on top right of code editor → Copy to clipboard
● Edit your original post, delete the cropped code text, paste the URL.
● Delete your answer, I will then also delete this note as I see you update the post with code attached.

May you find your solution.
