Accuracy of BME280 in high range of humidity

[Liza71]

 I want to use a Bosch Sensortec BME280 for my job. 

However I need to use this sensor in high range of humidity (more than 80% of relative humidity).

So, I would like to know if the accuracy of the sensor changes when the humidity is very high during a few hours, especially when it is a condensing environment (100% of Relative Humidity).

We don't have extra calibration certificates for our sensors, as the expected performance is already as listed in the specifications of the datasheet.
