what permissions should be assigned to end users of a site to be able to view and use the forms to edit or read or create data from interfaces

Please share the steps to assign respective permission. I have create a group and assigned couple of users to it (users are client who will use the site created in appian). They don't need access to tempo etc., but just site. They need to use the site as Content Management System to perform CRUD operations on MySQL Database.

what permissions should be assigned to end users of a site  to be able to view and use the forms to edit or read or create data from interfaces? Please share steps or guide on where to set which permission. The Application is made Restricted for members or admin only. Individual objects are assigned that new group called "SiteEndUsers". Now they are able to view but unable to submit a form to save in DB or update any records. I have tried assigning the users to Application Users group too, but did not work.
