Open the source files in IDE

when i am trying to open the source file in an online IDE, after typing
/home/crio-user/workspace/naman19179-iiitd-ac-ME_QEATS_REVIEW_MP/ and then click on ok it says please select a file

Instead of choosing option of “open file”, choose “open folder” & type location and press enter.
All the content will be available in the Left Side & choose the appropriate file for editing as mentioned in instruction.
Read the instruction carefully before proceeding.
