Problem with backstage-plugin-tyk plugin

Hi Tyk Community

I have a problem with backstage-plugin-tyk installation. Installation guide says that plugin could be installed via → yarn --cwd packages/backend add @tyk-technologies/plugin-catalog-backend-module-tyk command but it doesn’t exists in npm. Can you please suggest how can I install it for latest version of backstage? or maybe somebody can provide me happy path how to do that?
