Problem installing rasa x on ubuntu

I was able to install rasa on ubuntu and the next logical step would be rasax for training. I’m having trouble there can not install it. try to debug the errors created virtual environment with pip 3.8 to no avail here is what i get :
pip install rasa-x -i https://pypi.rasa.com/simple Looking in indexes: https://pypi.rasa.com/simple ERROR: Could not find a version that satisfies the requirement rasa-x (from versions: none) ERROR: No matching distribution found for rasa-x

Is rasa-x behind a paywall now? Is that why I get errors that no compatible version is available?

It was announced in June 2022 that Rasa X is no longer maintained or support.

Hello, Thank you for the reply. I was planning to develop an online customer assistant using my past communications with customers as yhe template and source of data. Can that be achieved with rasa?
