[Resolved] Is it possible to change the custom flag through the media folder

Problem:
The client needed to add alternative text to flag icons for SEO purposes. They were able to add alt text to SVG icons using the Optimole plugin but encountered issues when trying to add alt text to custom flags uploaded through WPML, as WPML only allows uploading flags from computer files.
Solution:
We informed the client that it is not possible to add alt text to custom flags through the media folder in WPML. However, alt text for flags should automatically be activated when the language switcher is set to display only flags, without the language name. We provided a link to the documentation on how to add a custom flag:
https://wpml.org/documentation/getting-started-guide/language-setup/language-switcher-options/custom-language-flags/#how-to-add-a-custom-flag
Additionally, we referenced a forum post that might help with the issue:
