What Jacob Gonzalez says is correct. You need the Network Master Key. You also need the Thread leader to let you into the network (typically done in whatever app they are using). I am not sure whether it is possible or not, using the kind of networks that you mention, but if you are going to try, the first thing would be to try to get hold of the network's master key.

Best regards,

You can only join an existing Thread network if you have the correct credentials, including the Network Master Key, which usually must be obtained from the commissioner or border router managing that network. If you’re dealing with commercial ecosystems like HomeKit, those credentials are typically not exposed, so commissioning a new device through the vendor app is often the only practical method. @fnf
