Multiple lines of text (Rich text vs Enhanced), hide image picker

@aseem,

Use this code to remove the Insert Image button from the toolbar:

const noteField = fd.field('Field1');
    noteField.widgetOptions = {
        tools: noteField.widget.options.tools.filter(x => x.name !== "insertImage")
    };

You can trigger flow from the form on button click. Please see the code example in this post: Start a sharepoint workflow from form button - #2 by mnikitina
