Joomla 4 and JCE compatibility

Hi,

We have a Joomla 3 website which we are planning to migrate to Joomla 4. We were using
https://www.joomlaworks.net/extensions/commercial/simple-image-gallery-pro
But the extension is not compatible with Joomla 4 and developer is not responding.

So, we are looking for an alternative gallery which is Joomla 4 compatible. Main reason we were using this gallery was its integration with JCE. It lets you create a gallery directly from JCE and you add it directly to the content you are editing. Website owner used it to add galleries in Joomla articles as well as in Virtuemart category descriptions. So, is it similar in your gallery extension?

Also, we will be working on staging a copy of the website. Is it possible to export galleries from staging copy and import on production website?

Please let me know. If yes, then my boss will make purchase asap.

Thank you.
