Is it possible to retrieve the unique block id or the machine name in the build() method of a block? When creating multiple instances of the same block definition, I can't manage to get a unique value per block from within the block methods (like for example the ID that gets appended to the machine name, or the machine name itself). I tried out all methods and properties of the BlockBase class, but no results.
Thanks in advance for any help on this.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Moving this up to the next major version, in the meantime, the workaround in #10 does the trick. I will note that blocks need to be resaved before the new info is stored in the the configuration.
#10 seems to only work for non-Layout Builder instances. Otherwise the callback_object in layout builder does not have a getEntity() method and fails.
