Need Help -Stand-alone Leaflet Map HTML Created -Want to integrate into TW -Import Or iFrame

I have created a map using QGIS and using its qgis2web Leaflet plugin. It is a stand-alone html file which has layers and zoom, etc. similar to online maps and does not require any retrieval of online data, APIs, etc…

How could we import a leaflet html file or the leaflet portion so that it can be seen as a tiddler? Does anyone have some suggestions on this?

What about showing the html file in an iframe:

<iframe src="file.html" style="border:none;height:520px;width:100%;" title="any title">

Example iframe of a leaflet map standalone. I think as long as it is in the same directory or perhaps the ./files directory you should be good.
