Configure IdentityServer4 ConfigurationStore and OperationalStore in a Multi-Tenant Environment

We have a web API that used IdentityServer4 for authentication. I am trying to change the authentication service to support multi-tenancy by keeping existing DBs. So there are separate DB for each tenant.

I am currently struggling to configure ConfigurationStore and OperationalStore.

Option 01: Since we have separate DB for each tenant, ConfigurationDb and PersistedGrantDb related tables can be added to those DBs.

Option 02: Use common DB to keep ConfigurationDb and PersistedGrantDb related tables.

What would be the best approach?

services.AddIdentityServer()
    // this adds the config data from DB (clients, resources, CORS)
    .AddConfigurationStore(options =>
    {
        options.ConfigureDbContext = builder =>
            builder.UseSqlServer(connectionString,
                sql => sql.MigrationsAssembly(migrationsAssembly));
    })
    .AddOperationalStore(options =>
    {
        options.ConfigureDbContext = builder =>
            builder.UseSqlServer(connectionString,
                sql => sql.MigrationsAssembly(migrationsAssembly));

        // this enables automatic token cleanup. this is optional.
        options.EnableTokenCleanup = true;
        options.TokenCleanupInterval = 30; // interval in seconds
    });
