Pea shingle instead of horticultural grit?

Unfortunately garden centres in Scotland are still closed 😔 Due to heavy clay soil I always try and incorporate lots of grit before planting but struggling to get a hold of it. I did manage to get some pea shingle but not sure if this would have any negative effect on the soil/ plants.
Any thoughts appreciated 🙂

Using grit in a planting hole can result in a " sump " where water collects and doesn't seep back into the soil around it.
If and when you do feel you need to dig use a fork rather than a spade and when you plant, add some organic matter to the planting hole and its surrounding soil. Well-rotted garden compost, leaf mould, well-rotted manure will be fine as will spent compost from pots, cheap MPC compost or soil conditioners you can buy at the DIY or GC.
I started my own compost bin last year so hopefully I’ll have some of my own stuff out of that in the next month 🤞
Adding the mature is making such a difference although the digging is tough work!
Adding in compost has really helped the flower borders but my lawn is still a mud bath
