Authentication operation of "LE Secure Connections (LE Security Mode 1: Level 4)"

I have a question about "LE Secure Connections (LE Security Mode 1: Level 4)".

I recognize that it is impossible to realize "LE Security Mode 1: Level 4" when adopting "Just Works".
In order to realize "LE Security Mode 1: Level 4", it is recognition that authentication operation (Passkey Entry or OOB or Numeric Comparison) is necessary.

Is my recognition correct?
