Hello Laura,

You can try this "groups" attribute like this : groups="crm.group_use_lead"

Hi,

yes with attr group in the button it work.

Thanks :)

Hi, 

Please check, is there a code that used the Capital letter of Group attribute instead the small "group" inside the xml code.

I guess, it used "Group="any group id" instead of  "group="any group id".

You can not use The "Group" inside the xml definition. Please try with "group".

Hope it will help you.

Hi 

You can use groups attributes like this

groups="module_name.group_name'

<button string="Create Button" type="object" name="action_create_button" groups="base.group_user" />

Regards
