Hi,
Can someone provide wiring details of how to connect the mini 0.7 / 19mm led matrix to a Max7219 please? I have code that works with Max7219 and don't have the skills to translate it to the backpacks that normally come with the mini matrices. But hopefully do have the skills to connect pins together! Thank you in advance.

You'd only want to use something like the MAX7219 with the bare LED modules, like this:

The "backpack" products already include a driver IC and work over an I2C interface:

Hi, are they the same matrices as the ones that come with the backpack then? Can you provide wiring details to a Max7219 please?

Yes, the LED backpacks use the same LED modules. For example, the PID 870 backpack includes a PID 454 LED matrix.
We can not provide wiring specifics for the MAX7219.
The datasheets for the bare LED modules can be found on their product pages. That has the necessary pinout information for determining the connections on the LED module side.
