Zotero tools not showing on LibreOffice Writer

Hello,
I have Zotero installed from snap and LibreOffice Writer 7.3
On Zotero Tools>Adds-On the zotero LibreOffice integration is enabled, but on Writer there are no the usual tools and the extension manager does not show zotero.
In the folder /snap/zotero-snap/current/extensions/zoteroOpenOfficeIntegration@zotero.org there is the file install.rdf but if I click on it, is simply gets copied on the Downloads folder. If I try to add it from the extension manager, I get en error (file not good). I can't access snap... because it is a hidden folder and extension manager does not allow to browse on them.
How can I re-install (the tools were there few days ago) zotero on Writer?
Thank you
