How to set up a computed var in Vue to change the vue-bootstrap badge variant color

I am attempting to set up a computed var in Vue to set the variant of a bootstrap badge tag <b-badge> depending on data being returned from a JSON file.

I set up the response returned from the JSON file to be passed to an array called configData. I then set up the computed var in my Vue component to look like this:

computed: {
   dynamicColor() {
      return this.configData.permission === "Env" ? "primary" : "success"
   }
}

Inside the computed var, when the permission property is set to "Env", then the variant property in b-badge tag...

<b-list-group v-for="data in configData" :key="data.id">
    <b-list-group-item>
        <div>
            <h5><b-badge pill variant="\(dynamicColor)">{{ data.permission }}</b-badge></h5>
        </div>
    </b-list-group-item>
</b-list-group>

...will be set to "primary". Otherwise, if the permission property is set to another value in the JSON, then variant will be set to "success".

Here is the full component:

<template>
    <div id="config">
        <h3><b-icon icon="wrench"></b-icon> CONFIG</h3>
        <b-list-group v-for="data in configData" :key="data.id">
            <b-list-group-item>
                <div>
                    <h5><b-badge pill variant="\(dynamicColor)">{{ data.permission }}</b-badge></h5>
                </div>
            </b-list-group-item>
        </b-list-group>
    </div>
</template>

<script>
import axios from 'axios'

export default {
    name: 'Config',
    data() {
        return {
            configData: []
        }
    },
    created() {
        this.getConfigData()
    },
    computed: {
        dynamicColor() {
            return this.configData.permission === "Env" ? "primary" : "success"
        }
    },
    methods: {
        getConfigData() {
            axios
            .get('data_config.json')
            .then(response => (this.configData = response.data))
        }
    }
}
</script>

I'm not sure how to configure variant in the b-badge tag to receive the computed var. I tried adding "\(dynamicColor)" to variant, but this did not work.

How can I configure variant to receive the computed var? Or is there another way to handle dynamic coloring for the badge based on data returned from JSON?

As with any other bound attribute in Vue, the syntax is the following:

<b-badge pill :variant="dynamicColor">{{ data.permission }}</b-badge>
