I've got a similar issue on my rear bumper. Epoxy will only hold for a while then it will break away again (I've had that happen on something else I repaired). There is a specific "difficult plastics" adhesive from 3M but it's quite expensive. Trying to plastic weld is going to be a one sided repair (as the back side has no real access) which may not be strong enough.

Use a soldering iron. Poke it into the crack, melting both sides and then while it's molten, smush it back together. If you want to reinforce it, aluminium filler mesh does an excellent job.

Your repair you said was abs, which is very easy with acetone slurry. I've done worse damaged, bike fairing repairs with it.
Yes soldering iron plastic welding looks the best option, I will need to find some PP filler rod from household junk items..

If you have the old panel clip a bit off that. I find solder station heat guns are excellent for plastic repairs as you can totally control the temperatures.
Epoxy only works if you can engineer the joint so it locks together when cured I find.
Provided you're an octopus or have a helper
You can always trim a bit off the same panel from the inside back edge with a stanley if you need some filler, but you're aiming for a near full penetration fusion repair if you can get in at it, rather than a surface fillet.

I dislike the staple types, seems a bodge. Ok as reinforcement but not on its own.
staple + paste over it with filler rod after. Or sink stainless mesh into the repair zone and paste over that. Your welding and adding reinforcement.
I've glued brackets and stuff onto cars using this technique sucessfully on multiple occasions.
You can buy sticks of filler rod in whatever plastic type you need to do the repair, or just slice a bit off the panel elsewhere as already suggested.

I've got nearly 5L of acetone, and some MEK, thinners, some DCM...
They make paint spraying pots out of PP as its resistant to everything.
I did plan to do the repair first but it can now wait, its got a coat of epoxy primer on the previously painted surfaces.

Is that Welsh for "higher"?

An adhesive "might" work if you do a little engineering. If the panel is thick enough you could try opposing 45 degree knife cuts...this will give the adhesive something (mechanically) to lock into with enough area.
Doesn't always work ..and may fail if the panel flexes (but say the adhesive is rigid) so needs some prior testing.
