Please replace your const addButton code with this code.

this is your code

    const addButton =
        customOptions && customOptions.length > 0 ? (
            <a
                
				id="productFullDetail.addItemToCart1"
                target={'_blank'}
                class="w-full text-xs tracking-[2.4px] h-[38px] text-[0.7rem]"
            >
                <button
                    
                    class="tryVirtualButton-root-aqT bg-[#F8F3EC] border-2 border-[#EFEAE2] p-2 w-full rounded-sm h-[38px] product_button"
                    type="button"
                >
                    <span class="button-content-TD8 gap-1.5 grid-flow-col inline-grid items-center justify-center justify-items-center">
                        <span class="text-[#181A1D] tracking-widest font-semibold">
                            {isStoreUser ? 'SELECT' : 'BUY NOW'}
                        </span>
                    </span>
                </button>
            </a>
        ) : isSupportedProductType ? (
            <div class="w-full text-xs tracking-[2.4px] h-[38px] text-[0.7rem]">
                <VideoCallButton
                    item={item}
                    urlSuffix={productUrlSuffix}
                    isStoreUser={isStoreUser}
                />
            </div>
        ) : (
            <div className={classes.unavailableContainer}>
                <Info />
                <p>
                    <FormattedMessage
                        id={'galleryItem.unavailableProduct'}
                        defaultMessage={
                            isStoreUser
                                ? 'Currently unavailable to select'
                                : 'Currently unavailable for purchase.'
                        }
                    />
                </p>
            </div>
        );

with this code

    import AddToCartButton from '@magento/venia-ui/lib/components/Gallery/addToCartButton';

    const addButton = isSupportedProductType ? (
        <AddToCartButton item={item} urlSuffix={productUrlSuffix} />
    ) : (
        <div className={classes.unavailableContainer}>
            <Info />
            <p>
                <FormattedMessage
                    id={'galleryItem.unavailableProduct'}
                    defaultMessage={'Currently unavailable for purchase.'}
                />
            </p>
        </div>
    );

then check and check some small errors if happen after replacing the code and accept the solution if it is working.

Thanks.
