How do I apply Elastic.Apm.StackExchange.Redis to Microsoft's IDistributedCache?

Like the title says, how do I apply Elastic.Apm.StackExchange.Redis to Microsoft's IDistributedCache?
The package exposes an UseElasticApm extension method to IConnectionMultiplexer, but the IDistributedCache creates its own multiplexer, and doesn't expose it.

APM Agent language and version: dotnet 1.12.1

Original install method (e.g. download page, yum, deb, from source, etc.) and version: NuGet

Unfortunately, it's not possible to get at the underlying IConnectionMultiplexer in Microsoft.Extensions.Caching.StackExchangeRedis 5.x.

It is however possible in 6.x, using RedisCacheOptions.ConnectionMultiplexerFactory:
