SQL Server 2019 log shipping setting error on Linux. 'Log shipping is not installed on this instance'

Hi,

We have running SQL server 2019 on CentOS 7.
The error we get when we try to enable log shipping is:

RegQueryValueEx() returned error 2, 'The system cannot find the file specified.'
Msg 22001, Level 1, State 1
Msg 32018, Level 16, State 3, Procedure master.dbo.sp_add_log_shipping_secondary_primary, Line 129
Log shipping is not installed on this instance.

Can't figure out what the problem is.
Have you seen this error or have any tip on how to solve it?
