How can I open a port in Matlab 2021 version?

In the following program I need to start a connection with a COM port, but I'm getting this error on line 22, and I think is because I dont have the right syntax, can somebody tell me how should I write it in MATLAB 2021.

You do not need to use fopen when using serialport.

See this page: Transition Your Code to serialport Interface

As an example, the equivalent for the following code using serial

s = serial("COM1");
s.BaudRate = 115200;
fopen(s)

is this using serialport

s = serialport("COM1",115200);
