I first tried the dotMatrix on the Arduino with the Sprite and Matrix libraries. I got funny results because the column adressing is reversed.
Therefore I switched to the MD_MAX72xx libraries. Make sure to change the define in the MD_MAX72xx. h file to read:
#define USE_FC16_HW 1
I used the MD_Keyswitch library found at https://github.com/MajicDesigns/MD_KeySwitch
and the MD_MAX72xx library found at https://github.com/MajicDesigns/MD_MAX72XX
Then I pulled the source at https://github.com/MajicDesigns/MD_MAX72XX/blob/master/examples/MD_MAX72xx_ScrollChart/MD_MAX72xx_ScrollChart.ino
With that you should be able to get it to work.
If you use pins that are not-SPI standard, make sure to activate the call to MD_MAX72XX with four parameters, and comment out the one with two parameters.

very good product and good price.
If you don't know how that work i found one good tutorial.
https://www.makerguides.com/max7219-led-dot-matrix-display-arduino-tutorial/
If you try the programs and see that they do not work with the first one.
Try changing the names of the pins you will use and reload the program on Arduino.
e.g.
CS_PIN 10
DATAPIN 11
CLK_PIN 13
