Hello, sorry, I don't know how to speak English, I have translated so that you can understand my query, I am willing to create an App to share trips. I was looking at how to put a notice in the passenger's app with a message that notifies them that the car is nearby and the other question is how to allow a driver to publish their trip in the App to get their passengers. If anyone can help me with any of this, I will be eternally grateful.
