Ideas on how to pull this tub apron out?

[Hult83]

So my tub was pushed inward near floor and I’m trying to figure out a non evasive way of pulling it back out and re caulking it.

I think the water caused the subfloor to swell and is keeping in pushed inward.

I was going to use a oscillating multi tool to try and take away some of the subfloor enough to get a thin pry bar underneath the tub and pull it out but I was curious if anyone has a better approach?

Is that a fiberglass or a steel tub?

Perhaps some suction cups? I bought Moen brand suction cup grab bars to lift tubs with. If you can get in from one of the ends, you could potentially use a deflated football to inflate and open up the space.
