Need help with a PUT request to Google Sheets

I want to get/put some data from/to GSheets. I easily get data from GSheets.
But i cant put data to GSheets.
Can anybody help me, please?

My app: Googlesheets123 | Bubble Editor

What’s the problem you’re having here, I’m not entirely clear?

Wanted to say thanks, I’ve been struggling for hours and hours trying to get the put request to work from Bubble (working fine from Postman), copying your Content-Type header was exactly what I needed!
