Can tempo distributed receive search traces from azure storage accounts

I would think that it would be able to since I can store the trace data, but I am having issues configuring the querier properly because I am not sure the values that should truly be set for the following:

querier.config.search.external_endpoints &&
querier.config.search.external_backend

so, at this point I just have traces sitting in the storage account, but all of my queries from grafana only access what still exists within the querier local
any help would be greatly appreciated
