How to handle search param with list as value?

[masterodi]

Let's say I want to create an url like this: <url>/whatever?filter=val1&filter=val2&filter=val3.
How would I do this?

I was trying to use setSearchParams: setSearchParams({...searchParams, filter: ['val1', 'val2', 'val3']}) but with no success.

Is there any way to add/remove from a search param which has a list as value?
