I understood that you want to use HTML at Gmail add-on. If my understanding is correct, how about these sample scripts?

Sample script 1 :

function buildAddOn() {
  var html = HtmlService.createTemplate('<b>Hello, world!</b>').evaluate().getContent();
  return CardService.newCardBuilder()
  .setHeader(CardService.newCardHeader().setTitle('sample'))
  .addSection(CardService.newCardSection().addWidget(CardService.newKeyValue().setContent(html)))
  .build();
}

Sample script 2 :

Code.gs

function buildAddOn() {
  var html = HtmlService.createTemplateFromFile("index").evaluate().getContent();
  return CardService.newCardBuilder()
  .setHeader(CardService.newCardHeader().setTitle('sample'))
  .addSection(CardService.newCardSection().addWidget(CardService.newKeyValue().setContent(html)))
  .build();
}

index.html

<b>Hello, world!</b>

Result :

Note :

As a sample, Manifests was used from Quickstart.
This is a very simple script. So please modify it for your environment.

If I misunderstand your question, I'm sorry.

@Robert I have never tried it for gmail add-on. So I'm not sure whether the custom forms can be created. But it's worth a try.
