Deprecated Warning Errors

Hi, Please Update the plugin and address the deprecated warning issues. I recently upgraded my PHP version to 8 as it is the standard now. But the Plugin has deprecated issues.

Deprecated: Using ${var} in strings is deprecated, use {$var} instead in C:\xampp\htdocs\website\wp-content\plugins\wc-paymongo-payment-gateway\vendor\posthog\posthog-php\lib\PostHog.php on line 176
