The trick to reading the Certification matrix is the Version Supported column will identify the "lowest" version of the product and for Discoverer the Install Type of must be "ALL".
For example, take a look at the certification matrix, the "FMW on WLS - DB" tab. The third row has Install type of ALL, naming the version as 188.8.131.52+. The plus sign means any version higher in that digit, meaning Fusion Middleware (FMw) 184.108.40.206.0, 220.127.116.11.0, etc.. It is important to always read the "Exceptions and Additional Information" column as well as the foot note for the * in DB version column.
You will see for this row it clearly states you must be at WebLogic Server (WLS) 10.3.6 and FMw 18.104.22.168.0 to use a 22.214.171.124+ database. This column also shows the 12.2 DB requires FMw 126.96.36.199.0. Discoverer is not a part of that release.
To directly address your question, No version 188.8.131.52.0 is not certified for any 12c database. Version 184.108.40.206.0 is certified for Database versions:
