Hello!
You have to pass address of the owner to Ownable constructor.
Here is your updated constructor:
constructor() ERC20("DecentralisedSTC1", "DSTC") Ownable(msg.sender) {}

msg.sender can be every address that will have access to modifiers from Ownable contract etc.
You have to add at least one of modifiers/override functions from this Ownable contract

Great heads-up
