How to attach carry potty to pushchair?

[RedRobyn2021]

I'm getting a train to London for a few days away with DD and my mum

Just realised I need to bring DD's carry potty... just wondering if there is a way to clip it to the little suitcase or the little jolie umbrella pushchair we are bringing as it's going to be a lot to carry

I'd have thought there would be something but I'm coming up blank

If the carry potty with the handle I just buckle mine to my back pack, it has two straps on that go over a pram handle bar but if not can you loop it through some bungee cord or similar and wind it between the two handles on the pram or tie it to the suitcase handle if you don’t have time to buy any carabiners - Amazon / JoJo bebe sell them

I hook mine on with a large caribiner
