Google Sheet Preview: is there any way?

What about a button in the composer that adds the iframe when clicked? It’s certainly doable in a Theme Component.

javascripts/discourse/api-initializers/init.js

main


      
          api.onToolbarCreate((toolbar) => {
            toolbar.addButton({
              id: "add-graph",
              group: "extras",
              icon: "chart-line",
              title: themePrefix("graph.graph_button_title"),
              perform: (e) =>
                e.applySurround(
                  '[wrap="graph-embed"]\n',
                  "\n[/wrap]",
                  "graph_equation_placeholder"
                ), // add_desmos_graph_euqation is a locale string: edit the text in locales/en.yml.
            });
          });

You can then change applySurround to addText and add the iframe content directly.
