how to sync existing members to acymailing

Hi,
i have recently moved to Joomla 4 and have migrated across membership pro and my list of existing members.
I have setup the acymailing plugin to place new signups to memberships in a certain mailing list, but how do I sync existing memberships into acymailing?

can anyone help?
In Joomla 3 there was a page you could access that would force the acymailing plugin to run and ensure all current subscribers were added (rather than just adding the new subscribers as they are added one by one)

Sorry. I missed your questions. You can try the steps below :

1. Login to administrator area of your site

2. Access to this URL

domain.com/administrator/index.php?optio...ve_event&plugin=acym

Replace domain.com/administrator with administrator URL of your site.

Then check the result, it should work. I don't know what page in Joomla 3 you are talking about, but that's not something from Membership Pro

Regards,

Tuan
