It is normal that all of these require manual connection (as per https://snapcraft.io/docs/supported-interfaces none of these are auto-connected by default). However, you can request that an assertion from the snap store be granted which can specify that these are auto-connected for your snap - see Process for aliases, auto-connections and tracks for more information. In this case, you could simply change the title of this existing thread and post a comment asking for auto-connection.
