DFRobot EC library failed to import into IOT Cloud (uno R4)

Hi, I wanted to add the DFRobot EC library for the uno R4/ IOT Cloud, unfortunately I get the following error:

 

Error while importing files

DFRobot_EC_Test: Error: no .ino fileDFRobot_PH_EC: Error: no .ino file

 

 

I used this library:

GitHub - DFRobot/DFRobot_EC: Arduino library for Gravity: Analog Electrical Conductivity Sensor / Meter Kit V2 (K=1.0), SKU: DFR0300

 

I followed the instructions from here

Importing files to the Web Editor | Arduino Documentation

 

 

I am happy about any help
