Generate deep links to file in channel

Question

Hello,
We are creating a deep link to file in a Microsoft Teams channel.
The deep link doesn't work for docx, ppt, pptx among, others. Seems like office docs don't work.
We are following the documentation here: https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/build-and-test/deep-links?tabs=teamsjs-v2#generate-a-deep-link-to-a-chat
The link format is this one: https://teams.microsoft.com/l/file/<fileId>?tenantId=<tenantId>&fileType=<fileType>&objectURL=<objectURL>&baseUrl=<baseURL>&serviceName=<Name>&threadId=<threadId>&groupId=<groupId>
Another problem we have is that the links don't work on mobile devices (Android and iOS).
Any suggestion?
Thanks in advance.
