Text() with AtributedString don't show the NSAttachment image in swiftUI

I have a problem when signing an AttribuedString to a Text(), the text is shown but the image in the middle if the text isn't.

var body: some View {
    if #available(iOS 15.0, *) {
        Text(messageString)
    }
}

@available(iOS 15, *)
private extension BookingPaymentView {
    var messageString: AttributedString {
        return AttributedString(self.viewModel.text)
    }
}

text content is provided from a external SDK and if I print the content I get this:

some text {\n    NSColor = \"<UIDynamicCatalogColor: 0x600001facf50; name = Neutral>\";\n    NSFont = \"<UICTFont: 0x14b410660> font-family: \\\"PublicSans-Regular\\\"; font-weight: normal; font-style: normal; font-size: 14.00pt\";\n}{\n    NSAttachment = \"<NSTextAttachment: 0x6000014b9ea0>\";\n}. Learn more{\n    NSColor = \"<UIDynamicCatalogColor: 0x600001facf50; name = Neutral>\";\n    NSFont = \"<UICTFont: 0x14b410660> font-family: \\\"PublicSans-Regular\\\"; font-weight: normal; font-style: normal; font-size: 14.00pt\";\n}

In the app, I can see the text "some text . LearnMore" without the image in-betweeng "text" and "."
