Kaltura Api php question. Replacing string content

Re: https://github.com/kaltura/Tags-Editor?files=1

Hi,

What file would I have to edit to automatically strip @gmail.com off any tags and auto update the records? Say a video is tagged with [email protected]…I’d like to replace that tag with xyz. I need this to satisfy a Zoom/Kaltura/Blackboard integration. I need a script to automatically do it ....no submit buttons as such. I tried str_replace but was hoping a PHP Ninja could see the solution. Thanks
