Does Android Topics API & Chrome Topics API share the same classifier model

[relevance-api-topics]

Hi Topics API experts,

Is the classifier model shared between Android (by app name) and Chrome (by host name)? (to check if it's valid to use Chrome tool to infer App topics)

Thanks!

based on further checking technically we should regard web and app as different models (might be derived from the same)
