As already mentioned by my collegues, the BME688 Sequential mode is not detailed in the latest BME688 Datasheet (BME68X_ODR3_MSK/Apr2021)
My first question would be -- is there a modified Datasheet that does describe this mode?
Otherwise, I would like to understand the timing of this mode. After reverse engineering the Sequential mode demo code, I see that the mode field in reg Ctrl_meas gets the value 3 to select Sequential mode. Furthermore, there are 2 additional fields that specify a so-called "sleep duration during Sequential mode" -- which I don't fully understand. I see that this sleep-duration (saved as odr field in a memory structure) is saved in 2 bit fields (odr20 & odr3) in registers 0x75 and 0x71 respectuflly. The odr bit combinations map to delay times as follows:

Hi amitr,
Currently, BME688 sequential mode timing was not open in document. We need to check whether we will open it in the future.

Hi amitr,
Could we know detailed information about your application?

Since there was no feedback for a long time, we close this topic first. You could update feedback in the future if you have.
