7 Segments LED + Arduino Nano

Does anyone have an idea how to configure new screens for the 7-segment LEDs connected to an Arduino nano?

Currently I am making an LED dashboard that consists of 2 LED modules with 7 segments of 8 digits each, an RGB LED strip with 24 LEDs, so far everything works perfectly but if I want to add a new message, for example, when it is activated The DRS in F1 2023, I want it to say DRS ONN for a few seconds it does not appear, only the messages that are configured by default in simhub appear.

The same with the intensity adjustment, if I adjust the intensity of the 7-segment LED, a message appears with the intensity value, but if I want to add one for the LED strip following the same parameters, it does not appear.
