How to get SpacePermissions using Java Confluence API (> 7.3.0)?

Earlier we used to get Space Permissions using below code

com.atlassian.confluence.spaces.Space space = spaceManager.getSpace(spaceKey);

List spList = space.getPermissions();

But now we are upgrading to Confluence 7.13.4 and spaceManager.getSpace(spaceKey) is deprecated and I can’t find a way to pull com.atlassian.confluence.spaces.Space which has most of the information.

According to Confluence 7.13.4 API ( SpaceManager (Atlassian Confluence 7.13.4 API) ) " since 7.3.0, use SpaceService.find(Expansion...) in plugins and SpaceManagerInternal in core where applicable ", So when I use above method to pull Space it returns a new Space ( com.atlassian.confluence.api.model.content.Space) class instance with minimum details unlike old one.

When I try to use SpacePermissionManager (SpacePermissionManager (Atlassian Confluence 7.13.4 API)) or PermissionManager methods accept only com.atlassian.confluence.spaces.Space but not new Space ( com.atlassian.confluence.api.model.content.Space)

Without the old Space (com.atlassian.confluence.spaces.Space) class I couldn’t find a way to pull SpacePermissions.

Thanks in advance!!
