Accessibility Checker gives this violation

Accessible name does not match or contain the visible label text

against

<button aria-label="text" type="button">
    <svg alt="text" focusable="false">
        <defs><style>.cls-1{fill:none;}</style></defs>
        <rect class="cls-1" width="32" height="32"></rect>
        <title>text</title>
