Using @SVGR/cli with a template example is throwing `SyntaxError: Cannot use import statement outside a module`

I'm using SVGR's CLI tool to try to create a template for a MUI-compatible React icon that works with Next. Per their docs:

Template

Specify a template file (CLI) or a template function (API) to use. For an example of template, see the default one.

Default CLI Override                API Override
basic template         --template   template: <func>

You can see they point to the project's defaultTemplate.ts file, which looks like this:

import type { Template } from './types'

export const defaultTemplate: Template = (variables, { tpl }) => {
  return tpl`
${variables.imports};
${variables.interfaces};
const ${variables.componentName} = (${variables.props}) => (
  ${variables.jsx}
);
 
${variables.exports};
`
}

I've tried to lay out a quick yarn project that looks like this:

/

package.json

{
  "devDependencies": {
    "@babel/core": "^7.0.0",
    "@svgr/webpack": "^6.2.1",
    "babel-loader": "^8.0.6",
    "webpack": "^5.68.0"
  },
  "scripts": {
    "build": "npx @svgr/cli --typescript --memo --svg-props preserveAspectRatio='xMidYMid meet' --template ./template --out-dir dist -- icons"
  }
}

template/

mui.template.ts

(Same as the default template)

package.json

{
  "name": "mui.template",
  "version": "1.0.0",
  "type": "module",
  "description": "MUI icon template for SVGR",
  "main": "mui.template.ts",
  "author": "Me",
  "license": "MIT"
}

But no matter what I do, it complains at me:

Error when loading "--template": ./template

.../next/template/mui.template.ts:1
import { Template } from '@svgr/babel-plugin-transform-svg-component';
^^^^^^

At first I assumed this was because I was missing a package.json with {"type": "module"}, then I read some stuff about making it a .mts file, or perhaps some incorrect dependencies, but nothing I've tried seems to be working. How can I make this template file behave like a module?

Update: I know now that this is definitely something in @svgr (or my local?) that is forcing < ES6 import syntax. Rewriting with require() and module.exports = works. Just have to figure out how to force it to run in ES6 mode.
