Thank you for your answers.
The DM3AT-SF-PEJM5 datasheet doesn't provide much information on wiring (maybe so and I just don't know how to read a datasheet). Here it is a link to download it:

I saw the datasheet for the DFRobot module, and so I thought I could create one myself because the Pico's 3.3V output makes wiring easier.
But on this schematic, I was wondering if C31 and C32 (filter capacitors maybe?) should be re-inserted on my schematic, and the same goes for R30 to R35? And if so, what is the purpose of these resistors?
PS: Sorry if my questions seem stupid, this is my first electronic project and despite my extensive research, not everything seems clear to me...
