Asynchronously retrieve client secret from secret manager before assign

[pex-tw]

Hi,
I would like to know what is the best way to get client secret asynchronously from external source in the AddAuth0AuthenticationClient()

builder.Services.AddAuth0AuthenticationClient(config =>
{
    config.Domain = domain;
    config.ClientId = builder.Configuration["Auth0:ClientId"];
    config.ClientSecret = // asynchronously retrieve secret from external 
});

You would fetch it before assignment:

var externalSecret = await client....

builder.Services.AddAuth0AuthenticationClient(config =>
{
    config.Domain = domain;
    config.ClientId = builder.Configuration["Auth0:ClientId"];
    config.ClientSecret = externalSecret 
});

If you wanted it baked into the builder.Configuration then writing your own configuration source that loads it from your source is also an option.
