Image to Oled on ESP32 Wroom

I have a oled screen and LED's attached to my wroom thant is in a convoi exceptionnel car.
I programmed the lights to the right channels (didn't tested jet if it works)
But i also want to show a arrow blinking or the text: "Convoi Exceptionnel" on the OLED.

But i'm lost in the forrest and can't find the right way out.
Who can help me program?
