access to a globalktable or aglobalstore from a different application - kstream

Question

we have 2 microservices:

1. responsible for consuming message and update a globalKtable with configuration information (key=id, value=myObject)

2. once it is activated with some id as an input it should look into the configuration globalKtable and retrieve data by that id

how is it possible to access that globalktable from app2. should a REST layer be added to retrieve the info or Stream has some other capabilities?

Thanks
