No dongle will help with only one native external monitor.
2019 Intel MBP has no native external monitor support. It's dongle hell all the way down.
But at least it can use a dongle to utilize 2 or more external monitors. The point is the base M1/M2/M3 cannot use 2 external monitors. At all. No matter how many dongles you buy.
It has native support for 4 external thunderbolt displays.
