What is the right way to override the ContentBody HTML in 4.3?

[mudrd8mz]

From what I can understand from

chameleon/src/Components/MainContent.php

Line 59 in 3094d2f

$this->getSubComponentHtml( ContentBody::class, 'ContentBody' ) .

the MainContent component has hard-coded ContentBody as the class to provide the content body HTML.

What is the clean way to inject my own ContentBody subclass to be used instead?

My use-case is that in buildContentBody() I want to perform some DOM modifications and I am trying to find the clean way to customise it.

TIA
