Using attachment image inline in Send an email (V2) body

In my flow I've used a Compose to store the base64 string of an image.

In my Send an email (V2) I've setup an attachment:

[
{
"Name": "logo.png",
"ContentBytes": @{base64ToBinary(outputs('Compose_-_Email_Logo_Base64'))}
}
]

then in my body I've done

when I send the e-mail, the attachment is there, yet in the body all I get is a square with a red x stating "The linked image cannot be displayed. The file may have been moved, renamed, or deleted. Verify that the link points to the correct file and location.".

I've tried all sorts of variations which included things like adding

"IsInline": true,
"ContentId": "logo.png",
"ContentType": "image/png",

The only way I've been able to get it to work is to use an image hosted on a website and use that for the imge src (https://....)

Can anyone help me correct the <img > syntax to get this working with the compose base64 string to embed it directly in the message body. Since Outlook desktop doesn't support base64 images directly, I'm simply trying to find a way to replicate what I've long done in VBA which is to use the cid: approach, but can't find a way to do so in Flow.

Thank you.

Thank you for trying to help, but those examples rely on using a Sharepoint library which is not my case. Even if we ignore that, following the cid approach doesn't work in my context.

What I also notice is that even though I explicitly define

<img src='cid:logo.png'>

in the e-mail the source shows

<img data-outlook-trace="F:0|T:1" src="cid:419B869964E99B42954EA545012633FF@namprd13.prod.outlook.com">

???

Why is Flow changing my HTML?

I'm always amazes how complicated certain things are made to be in Flow. I'm already in 10-12 hrs of trying this and that, searching all over the place. This is a common need, nothing exceptional whatsoever, I've been doing things like this for years in a multitude of languages, yet it can't be done in Flow.

@DanielPineault Sorry for the delay...

My best would be to use
<img src='@{dataUri(body('Get_file_content_using_path:_Embed_Image'))}' />

I had that problem once, I switch to the classic UI, changed the email body to honor HTML and then inserted the snippet...
