If the modules do not have female or male pin headers and there is enough space, I solder those on. then I use a bread board and some wires with combination of female and male connecters on both sides to connect the components and modules. If there is not enough space I cut a wire with pins in half solder the cut end onto the module. The other end of the wire I plug into the bread board...
It is also very practical to have a power supply for the board that delivers - in your case 3.3V. Using a DC-DC (buck step down) converter with a USB plug that takes 5V from a USB and produces 3.3V output.
On many posts you can see how it's done, for example: Breadboard friendly PICO.
If you have not soldered yet, take some scrap things and practice on them. Go to youtube and search for some instructional videos.
