I use fetch (in React) with the DELETE method, execute a query with line (api understands the given value)

name-%{[@timestamp]}-1970.01.01

fetch(`/api/apiname/name-%{[@timestamp]}-1970.01.01`, {
        method: 'delete',
        headers: {
            'Content-Type': 'application/json;charset=utf-8',
            Authorization: `Bearer ${Token}`
        }
    })

like this, but when requested, I get characters in query line

Request URL: http://localhost:3000/api/apiname/name-%%7B[@timestamp]%7D-1970.01.01

that prevent it from being executed, how can I fix this?

I tried to use decodeURI but it didn't help

P.S. I need the request to be

http://localhost:3000/api/apiname/name-%{[@timestamp]}-1970.01.01

but not

http://localhost:3000/api/apiname/name-%%7B[@timestamp]%7D-1970.01.01
