java - Azure keyvault - springboot integration - Which is the minimum supported springboot version?

Question

My Parent project has springboot 2.0.6 and when I tried to use azure-spring-boot-starter-keyvault-secrets, the application failed to start with ClassNotFoundException. Spring Initializr says keyvault Requires "SpringBoot version >= 2.0.0.RELEASE and < 2.4.0.M1.". Your help is appreciated to figure out what am I doing wrong!

Full stack trace is as follows:
