Whether or not this integration should initialize the SDK. If you intend to call `SentrySdk.Init` yourself you should set this flag to `false`.

#### RestrictedToMinimumLevel

`MinimumBreadcrumbLevel` and `MinimumEventLevel` determine what the sink does with a log event, but every log event the logger captures still reaches the sink. If your logger's minimum level is verbose — for example, because another sink writes debug logs to a file — you can use Serilog's [per-sink minimum level](https://github.com/serilog/serilog/wiki/Configuration-Basics#overriding-per-sink) to stop lower-level log events from reaching Sentry entirely.

By default this value is `Verbose`, meaning no log events are filtered out. Ignored when `LevelSwitch` is set.

Bug: The documentation incorrectly claims RestrictedToMinimumLevel filters structured logs. This setting likely only affects breadcrumbs and events, not structured logs sent to Sentry.
Severity: MEDIUM

Suggested Fix

Verify the actual behavior of RestrictedToMinimumLevel in the sentry-dotnet SDK. If it does not filter structured logs, remove the statement "This also controls which log entries are sent to Sentry as structured logs" from the documentation. The filtering of structured logs should be attributed to the global MinimumLogLevel.

Potential issue: The documentation update claims that the Serilog sink's
`RestrictedToMinimumLevel` setting controls which log entries are sent to Sentry as
structured logs. This is likely incorrect. Based on the pattern in the
`Extensions.Logging` integration and existing Serilog documentation, per-sink level
filters typically only apply to breadcrumbs and events. The global `MinimumLogLevel` is
what likely controls structured log capturing. Users following this new documentation
may mistakenly believe they are filtering structured logs, leading to more data being
sent to Sentry than intended.

Did we get this right? 👍 / 👎 to inform future reviews.


#### LevelSwitch

An optional `LoggingLevelSwitch` that allows the sink's minimum level to be changed at runtime.
