Crrytomator-cli: java.lang.UnsupportedClassVersionError

I want to give a try with cryptomator-cli.
I use Ubuntu 22.04.3 LTS 64 bits, up-to-date.
When I run the command given in the doc, I’ve got this error:

$ java -jar /path/to/my/cryptomator-cli.jar --vault test-vault=/path/to/my/test-vault --password=mypassword --bind --port 8080
Erreur : LinkageError lors du chargement de la classe principale org.cryptomator.cli.CryptomatorCli
	java.lang.UnsupportedClassVersionError: org/cryptomator/cli/CryptomatorCli has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

I don’t know java’s world. Is this a version compatibility issue? What should I do to solve this?
Thank you
