Odx are supported

Fedora 39
onlyoffice-desktopeditors-8.0.0-99.el7.x86_64

My *.odx spreadsheets are supported, but I have to select all documents to get them to show when browsing documents (file → open). Please update the supported selection in file-> open to include *.odx

Hello,
please provide an example of the .odx file with which you faced the issue.

Will this do? I do believe odx is encrypted ods speadsheet , but I could be wrong.

We will consider your suggestion, thank you. Please await for further updates.
