Re-allow a website to access my location on mobile

Hi, Recently a website I use on my phone for work popped up with the little box asking for permission to access my location, and just out of habit I immediately denied it and ticked 'Don't ask again'. However, that was dumb because I do really need that website to be able to access my location and I can't figure out how to turn it on again. If I go into Settings=>Website Permissions=>Location, which I've read in other places I should do, my only two options are 'block' or 'ask for permission', so I've changed it back to 'ask for permission' but it hasn't asked me again and it's still not recording my location, despite restarting to tab, broswer, phone etc. What can I do? Thanks:)
