How to know if CPU of instance shared or dedicated?

[Ilyaemma]

HI.
How to know if a public cloud instance's CPU is shared or not?
I have found here https://www.ovhcloud.com/en/public-cloud/virtual-instances/ that "discovery" instances "offer shared resource" and here https://www.vpsbenchmarks.com/instance_types/ovhcloud some information about instances, but nowhere any official info about CPU instances type (shared or dedicated).
I also checked "Instance detail" of public cloud instance and there is no info about that.
Pls help.
