How to submit with enter in html?

I am trying to let people rate participants different words with a continuous rating scale and submit when they found are happy with their chosen position. Here is my code to do so:

<main class="content-horizontal-center content-vertical-center">
    <div>

        <div class="m-l" style="height: 200px">
            <p class="font-weight-bold">
                ${parameters.word}
            </p>
            <p class="m-l" style="height: 100px">
                ${parameters.Bewertung}
            </p>
            <form id="pumps-form">
                <input
                        type="range"
                        name="pumps" id="pumps"
                        class="w-100"
                        min="1" max="100" step="1"
                        value="0"
                >
            </form>
        </div>
    </div>
</main>

<div>
    <input type="submit" form="pumps-form"/>
</div>

The submission of the form works fine when they press a button at the bottom of the page. However, I would like to enable to submit the rating with a keyboard buttonpress.

I have tried to use accesskey and the code mentioned here: Submitting a form by pressing enter without a submit button

Also I trie to wrap the input with a form tag (Input submit with enter) which did not work either.

but both did not let me submit my code with a buttonpress.

Thank you!
