TJ and druidh are right, at least until druidh said to “own it”.
Bus lane, indicate right with plenty of time and move over to the normal lane when there is a gap and it is safe. If there is no gap because traffic is heavy, then you should be able to move across the bus lane, provided it is clear, and then very gradually over until you have a presence in the ‘normal’ lane.
However IMO that road is easily wide enough that you should ride about 1m away form the kerb and there is lots of space for a car to overtake.
/edit – I agree that you need to take an appropriate presence on the road but by “own it” I infer that druidh is advising you to “take the lane” and not allow space for traffic to pass, which given the width of the road I think is unnecessary.
