How to add turn restrictions to this junction (turn:lanes, relation, or …)?

1

I'm trying to map the service road at the NW corner of this junction: https://www.openstreetmap.org/#map=19/32.09684/34.82139

That road is currently marked as "one lane forward, one bus lane backwards" which is correct for most of it, but at the intersection it widens to two lanes in the forward direction. One of those lanes is "right turns only", the other is left-or-straight. (That's in addition to the opposite bus lane.) How do I add these restrictions?

I'm not sure whether I should just add turn:lanes:forward="left;through|right", or whether relation(s) are also required.

Turn restrictions are only necessary if there are roads which you are not allowed to enter and this restriction is not already implied by other access or oneway tags.

Supposed you are allowed to enter all roads then lanes:forward=2 and turn:lanes:forward=left;through|right are sufficient.
