useFetch update my data without assignment

Hi guys, I must have missed something, but I found something weird using useFetch. It looks like there's a kind of link between requests on the same URL. Here's my code for an example:

<script setup>
    /**
     * API fetch
     *
     * @param {String} url
     * @param {Object} options
     * @returns {Object}
     */
    const fetch = (url, options) => {
        return useFetch(url, {
            baseURL: apiUrl(),
            headers: {
                accept: 'application/json',
                'X-XSRF-TOKEN': useCookie('XSRF-TOKEN').value,
            },
            credentials: 'include',
            ...options,
        })
    }

    // Get a json object { test: 'get' }
    const { data: test } = await fetch('v1/test');

    const post = () => {
        // Get a json object { test: 'post' }
        fetch('v1/test', { method: 'POST' });
    };
</script>

<template>
    Test: {{ test }}
    <input type="button" value="Click me" @click="post"/>
</template>

<script setup>
    /**
     * API fetch
     *
     * @param {String} url
     * @param {Object} options
     * @returns {Object}
     */
    const fetch = (url, options) => {
        return useFetch(url, {
            baseURL: apiUrl(),
            headers: {
                accept: 'application/json',
                'X-XSRF-TOKEN': useCookie('XSRF-TOKEN').value,
            },
            credentials: 'include',
            ...options,
        })
    }

    // Get a json object { test: 'get' }
    const { data: test } = await fetch('v1/test');

    const post = () => {
        // Get a json object { test: 'post' }
        fetch('v1/test', { method: 'POST' });
    };
</script>

<template>
    Test: {{ test }}
    <input type="button" value="Click me" @click="post"/>
</template>

On the first load, my page shows Test: { "test": "get" }, that is what I wanted to do, fine. But when I click on the button, the page shows Test: { "test": "post" } and I don't understand why. I expected to see Test: { "test": "get" } again, as I didn't change the test variable by myself. Any idea? Thanks

maybe you want $fetch i use "useFetch" only for the first call https://discord.com/channels/473401852243869706/1075465297974263868

Ok I wanted to factorize all my API calls into a custom plugin to add them some options. But I assume that I just have to make a .get() function using useFetch, and post, put etc using $fetch ?
