Good unreasonable o'clock in the day. i have been reading your post and it seems like you are accomplishing something using esp32s3 and the BME680.
I have been trying ti do the same thing for a year now with the manufacturers help for the controller (lilygo t5_47 s3E-Paper v2.3) i thought the were helpful at first but they made a how to video that was in full speed from a senior engineer on a windows machine in chineese language. it was hilarious if nothing else.
I just want to make it work and you seem to have an idea as to what the hell is going on.
i noticed you are just getting back into programing (i think i read that), Im 45 and trying to get started to maybe have a hobby with my teenager.
My name is Craig Campbell i pray for kindness.
i will add that i believe i have learned how to get zip files from a site called GitHub into ardurino library manager. (is that right)
total goal is sensor data on the epd display after that i will figure out how to make it useful.
Thank you for your time if you do get to see this.
which specific BME680 module ? give a link?
using the I2C interface you should be able to connect the BME280 to pins SCL (17) and SDA (18) on the 40pin header
run the I2C scanner to check it finds the device
if that works try a BME280 example - initially output to the serial monitor
then look at outputting results to the display
