Consider some distraction work while you’re at it. Emphasize external rotation and gapping distraction with a power band. Floss in and out of extension end range 50ish reps. Combine that with some voodoo flossing and smash with a barbell. Sprinkle in some t spine mobility. Lost elbow rom may be a downstream effect of your shoulder being in a bad position so restoring T spine position and therefore shoulder position may be beneficial too.
