How to Setup to capture Monolog logs leading up to error as breadcrumbs

[rijnhard]

The docs are quite unclear (atleast for me)
The goal is to log exceptions and all the logs leading up to that exception in a Sentry Issue (I am using monolog).

At the moment I'm not clear how the monolog Logging settings affects that or doest, both of my attempts have failed.

Attempt 1 - with monolog logger

sentry.yaml

sentry:
    dsn: '%env(SENTRY_DSN)%'
    # https://docs.sentry.io/platforms/php/guides/symfony/#monolog-integration
    register_error_listener: false
    register_error_handler: false
options/
    options:
        environment: '%env(SENTRY_ENVIRONMENT)%'
        release: '%env(SENTRY_RELEASE)%'

monolog.yaml

monolog:
    handlers:
        main:
            type: fingers_crossed
            action_level: error
            handler: nested
            excluded_http_codes: [404, 405]
            buffer_size: 50
            channels: ["!event", "!doctrine", "!php"]
        nested:
            type: stream
            path: "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
            formatter: monolog.formatter.json
        console:
            type: console
            process_psr_3_messages: false
            channels: ["!event", "!doctrine"]
        sentry:
            type: sentry
            level: '%mk.sentry.log_level%'
            hub_id: Sentry\State\HubInterface
            channels: ["!deprecation"]

Attempt 2 - without monolog

sentry.yaml

sentry:
    dsn: '%env(SENTRY_DSN)%'
    # https://docs.sentry.io/platforms/php/guides/symfony/#monolog-integration
    register_error_listener: true
    register_error_handler: true
options/
    options:
        environment: '%env(SENTRY_ENVIRONMENT)%'
        release: '%env(SENTRY_RELEASE)%'

monolog.yaml

monolog:
    handlers:
        main:
            type: fingers_crossed
            action_level: error
            handler: nested
            excluded_http_codes: [404, 405]
            buffer_size: 50
            channels: ["!event", "!doctrine", "!php"]
        nested:
            type: stream
            path: "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
            formatter: monolog.formatter.json
        console:
            type: console
            process_psr_3_messages: false
            channels: ["!event", "!doctrine"]

I would like to know this too, currently all the logs are shown in the sentry as separate issues.
