WordPress doesn't allow us to edit posts and many other things via REST or with help of scripts.
To bypass this i used a Selenium.
It's included into requirements.txt so it will be automatically installed in Run sploit part.
Nevertheless to run sploit u need to install a chromedriver. You can find a chromedriver for your OS here.
Afer installing a chromedriver you can run sploit.
Make a virtual environment and activate it:
python3 -m venv venv
source venv/bin/activate
Install requirements:
pip3 install -r requirements.txt
Run a sploit:
python3 sploit.py
