@yamitzky Hello there! I'm here to help you with any bugs, questions, or contributions you have for the repository. Let's tackle this issue together!

The issue is likely due to the emailRegex used in the InviteModal component, which might not be allowing the "+" character. To resolve this, you need to update the emailRegex to include the "+" character. Here is an example of a regular expression that allows the "+" character in email addresses:

const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;

Update the emailRegex in your InviteModal component as shown below:

import { emailRegex } from '@/config';

// Update the emailRegex to allow "+" character
const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;

const handleSend = useCallback(async () => {
  if (emails.map((email: string) => emailRegex.test(email)).every(Boolean)) {
    try {
      const { result, invitation_results } = await inviteMember({
        url: '/workspaces/current/members/invite-email',
        body: { emails, role: role.name, language: locale },
      });
      if (result === 'success') {
        onCancel();
        onSend(invitation_results);
      }
    } catch (e) {}
  } else {
    notify({ type: 'error', message: t('common.members.emailInvalid') });
  }
}, [role, emails, notify, onCancel, onSend, t]);

By updating the emailRegex, the system should now correctly validate email addresses containing the "+" character and generate the invitation link as expected [1].
