Unable to use texture packs on realms

I have been playing realms with my friends and I wanted to build a farm and it would be useful for me to use a resource pack to see spawning spaces. However, when I went on global resources and put the pack on, it did not work on the realm. I tried relogging, reinstalling and restarting my pc but nothing worked. Pre 1.18 I could put the pack on and see the changes but not in the latest versions.
