How to re-enable local file saving on mindmanager web version ?

I use to save my mindmanager files on a local cloud through the "local files" tab, but you made it disappear in the last updates of the web version.
I want to keep this functionnality available, or at least, I would like to connect to a local cloud to save my files on a local basis. I already read a temporary solution, Sia gave in the following topic :
https://community.mindmanager.com/topic/2197-cant-work-with-local-files
But it's a possibility that must be implemented each time → Not really a solution...
Can you give us a solution to come back to a local storage, or open the possibility to connect to other cloud storages (nextcloud, pcloud, local clouds...).
Thanks in advance for your answser.
