Difference between COPY ONLY and TRANSACTION LOG BACKUP

We have setup with Log Shipping (LS) on the servers.

On the Primary Server apart from LS there are SQL Agent Jobs pertaining to procuring the Transactional Log backup for every 30 Minutes and this would store on the Different Drive separating from the LS Drive Backup Files.

Before setting the LS have disabled the SQL Agent related Transaction Log Backup and once LS is working then have Enabled the SQL Agent Transaction Log Backup.

By doing this arrangement will the LS breaks?

If not what are the alternative steps to run BOTH LS and SQL Agent Job for the Backups through LS and Transactional Log Backup through SQL Agent Job.

Could anyone Please suggest for the best arrangement not to clash.

Thanks in advance.
