LogicApp Standard - 413 Request entity too large

Question

In Order to work with files bigger than 105MB i made a LogicApp Standard where i can increase the limits.

The body of my POST-Request to the LogicApp contains a large Base64 string which is about 120MB.

Request Body JSON Schema:
{
"Id": 123,
"FileName": "Test01.zip",
"FileContent": "Base64String(~120MB)",
}

I've edited the host.json as following:

Similar to the answers from @MayankBargali-MSFT in this Post:

As you can see i tried several settings as mentioned in edit-app-settings-host-settings as well but nothing worked for me so far...

Error when testing with Postman:

No actions or errors in my workflow trigger/run history...

TIA

@PhilipAppenzeller-8936 Apology for the delay. The HTTP request length is limited to 100 MB by the underlying platform as documented here. I have got confirmation from my team that HTTP operation settings are only applicable when you use more than 100 MB in the workflow execution for the other built-in actions and not for HTTP trigger as this cannot be changed.
Unfortunately, you cannot send more than 100 MB to HTTP trigger. The workaround would be to upload the content to blob storage and then get the content in the logic app workflow from blob storage.

I will work with the document team to see if we can clarify this in the configuration document.
