Nextcloud matterbridge install

Looking for a little advice, trying to get nextcloud talk bridge to work . All the posts i find about this don’t have any answers really just questions.

Does the matterbridge setup work? I am using nextcloudpi and when i go to the talk admin page to install i get the “Failed to execute the matterbridge binary” and sometimes “install matterrbridge binary manually”

When i attempt to follow the instructions for manual install the occ command does not work to execute the .bin

Maybe I am missing something obvious?

Thanks
