Internal server error when trying to enable Shared Edits plugin

[milkii]

When I enable the Shared Edits and then try to use it, I get an Internal Server Error, and the log says a table is missing in the db.

ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR:  relation "shared_edit_revisions" does not exist
LINE 8:  WHERE a.attrelid = '"shared_edit_revisions"'::regclass
                            ^

Is there not a ./launcher available, like apparently with a standard Discourse install?

Enable shared edits gives internal server error message

Internal server error when trying to use official Shared Edits plugin

Plugin install method: GitHub - YunoHost-Apps/discourse_ynh: Discourse package for YunoHost

Any advice would be appreciated, thank you.
