How to Create a line break in WhatsApp messages [ReactJS Web]

Question

I'm trying to send a message from ReactJs to Whatsapp api But i can't create a content text with line break : ex:

Hello Shop,
I'm looking for this Shoes. Can you help me ?
--Name

This is my code that i tried with :

   <button onClick={
     () => window.open("https://wa.me/phoneNumber?text="Hello Shop,'\n'
      I'm looking for this Shoes. Can you help me ? '\n'
     --<Name>")}>
       Send Message
   <Button>

I tried with : '\n', '\r\n\r\n', '%0a', '%0D%0A',... But did not work.

linebreaks are "normaly" encoded by \n (LF), \r\n (CRLF).

for http GET parameters you also need to use urlencode.

line1="hello"
line2="world"
msg = encodeURIComponent(`${line1}\r\n${line2}`)
