How to install specific version of rasa x

I want to install rasa 0.21.3 instead of 0.21.4

I have only below command

sudo python3 -m pip install -U rasa-x --extra-index-url https://pypi.rasa.com/simple

Resolved by below command

sudo python3 -m pip install -U rasa-x --extra-index-url https://pypi.rasa.com/simple/rasa-x/rasa-x-0.21.3.tar.gz

You can find package from Package Index url and simply pass the package name with full url
