When users request access to our list and are approved, they are added as a single user instead of added into a group?

Question

I have a "Team Visitors" SharePoint permission group which give read and approve access to a list that has a form (Intake Form).

When users request access to this list, and we approve them, they are added as a single user to the permissions tab in the ribbon with "edit" access.

Is there a way to automatically send them into the "Team Visitors" group instead of being an individual entity on the permissions tab?

I do not want new members to join with "edit", I want them to be automatically added into "Team Visitors" which have "read" and "approve" access (in order to create a form and read the listview).

Edit:

I do not get the choice to select a permission group in the drop down of the approval prompt:

On the screen where you approve access, click the ellipsis, and then select the 'Permission' dropdown to grant rights or add them to a group.
