Matching a post with a memberId WIX

I’m trying to input the logged member ID into a CMS in Wix. I can’t find a way to do this without using code, and when I try to use code, it works but creates an additional item in the database just for the member ID insert.

I believe this happens because the other data I send im using the no-code method connecting the inputs to the specific table from the database for every input on the screen. The only way I found to insert the current logged member ID into the CMS is through JavaScript, but it’s sending twice: once via the no-code method sending all the data and once via code sending only the memberId. I can’t find a way to ensure everything is sent only once without creating 2 items in the database.

here is my code to send the memberId:

export function buttonSubmit_click(event) {
    currentMember.getMember()
    .then(member => {
        if (member) {
            const userId = member._id;

                const toInsert = { "userId": userId };

                wixData.insert("Empresas1", toInsert)
                .then(result => {
                    console.log("Item inserido com sucesso:", result);
                })
                .catch(err => {
                    console.error("Erro ao inserir o item:", err);
                });
        } else {
            console.log("Nenhum membro logado.");
        }
    })
    .catch(err => {
        console.error("Erro ao obter o membro:", err);
    });
}
